A pair of Dowty type sealable washers to fit 1/4 BSP Petrol Taps.  Price is for a pair of washers

These washers are a modern alternative to red fibre or copper washers for those petrol taps with 1/4BSP threads going into the petrol tank - of the type used on most Norton OHV, SV, Twins and CS1 models, as well as many other British motorcycles.

Note: in the photo on the left is a genuine Enotts style petrol tap as fitted to the Left side of many OHV/SV tanks of the 1940's.  This is identifiable because of the union at the base of the tap - which would have held an extension banjo to take fuel over to the other (drive side) fuel tap - which would have then fed the carburettor.  A domed nut was then used at the bottom, under the banjo fitting (rather than a fuel pipe to the carburettor, as on the drive side).  These taps are now quite rare - sorry, this one is not for sale.

These washers are not of the type used with the large 'Sump' type SOHC petrol tap - although we do sell the special red fibre washer for those taps - it being Item 0383

This item is for a pair of high quality red fibre washers - which are an exact fit on the modified/lipped main nut (Item 1095) we offer to fit early Amac HYK carbs - please read item 1095 description before ordering these, and note that if ordering the 1095 nut - it already comes with a pair of washers, this listing is just for a pair of washers on its own.

Note that (although I am no expert on early Amac carburettors) - the original Amac bottom nuts of pre-1920 era I have seen do not have a lip - and no washers were use - it just relied on a very shallow taper on the nut - which was easily damaged and leaked, hence why we manufactured the modified lipped nut.  However, this design seemed so likely to receive damage and leak.. . . it would not suprise to know that later (1920s) Amac or similar carbs used a lipped bottom nut (as indeed later Amal carbs did).

However, if you require spare washers for these Item 1095 nuts . . . or think you have another carburettor which requires similar size red fibre washers - then here are dimensions of these washers:

Inner Diameter = 14.2mm.  Outer Diamter = 23.5mm. Depth = 1.4mm

These are high quality vulcanised red fibre washers, sourced from our specialist washer manufacturer.  Price is per pair.

This item is a stainless steel oil/fuel pipe ferrule to fit black rubber style 5/16" internal diameter BSP pipe - of the type often used on Norton models for cambox pipes, breather pipes or similar - but this type will fit over pipe with an OD of 14mm. 

These are UK manufactured by a specialist ferrule maker.

Although 5/16" internal pipe bore is a standard BSP pipe size, it should be noted that many commercial fuel and oil breather pipes have different outer diameters - and therefore some ferrules will fit and others will not.  This particular ferrule is a good quality UK manufatured ferrule with an internal bore of 0.544"/13.8mm - meaning it will fit over fuel/oil pipes with an outer diameter of 14mm.  Notw we also manufacture ourselves a slightly bigger 5/16" ferrule, which will fit over pipes with an outer diameter up to 15mm - see Item 0979b (but they are CNC turned from solid stainless bar and far more expensive). 

Price is Each.

These ferrules can be crimped with a commercially available ferrule crimping tool - but often on breather pipes, all that is necessary (if the ferrule is a firm fit over the pipe, and is mainly to be cosmetic only) is to use a centre punch half way along the length of the ferrule to stop it slipping off.  If you are using it for fuel - as with all fuel pipes - it will require some form of crimping tool to ensu

This item is a stainless steel oil/fuel pipe ferrule to fit black rubber style 5/16" BSP pipe - of the type often used on Norton models for cambox pipes, breather pipes or similar.  These are CNC machined from solid stainless bar - to fit over a fuel/oil pipe of up to 15mm OD, as chrome ferThese are CNC machined from solid stainless bar, as chrome ferrules in this size are not easily obtainable.  

It should be noted that although 5/16" BSP pipe is a common BSP bore size - the outer diameter of this bore size pipe can vary considerably, and although we sell commercial pipe ferrules that will fit over 5/16" bore pipe with an OD of up to 14mm (Item 0979a), some 5/16" pipe (particularly the black rubber type) can have a bigger outer diameter - therefore we sometimes make small batches of these ferrules - which have an internal bore of 0.599" and can be firmly pushed over fuel/oil pipes of up to 15mm.

We already sell black rubber petrol pipe sets (Items 0121 and 0122), which use nice quality chromed steel 1/4 BSP ferrules to crimp the fuel pipes to the union connectors - however, similar looking (i.e.classic motorcycle type) ferrules for the larger 5/16" BSP style pipe have been unobtainable commercially for many years (to my knowledge) - so for one of my own projects, having not been able to find any suitable commercially available ferrules - I ended up writing the CNC programs to machine these from solid bar stock stainless steel.

The finished job is a very pretty thin walled ferrule, where the final gauge of the steel that covers the 5/16" pipe is comparable to normal chromed steel (1/4 BSP) ferrules.  The internal bore of these ferrules is 0.599"/15.2mm which should be an easy slide fit on most 5/16" bore BSP fuel/oil pipe, but please check before ordering - as the outside diameter of fuel pipes can vary by brand and type (the nominal size referring to the internal bore).

The ferrules are shouldered at one end (as most pipe ferrules are) and have a very pretty, non-rusting finish. 

You will need to decide for yourself how you attach them - there are various commercial crimping tools available, as for all ferrules - but again, if using motorcycle type crimping clamps intended for 1/4 BSP, you will need to satisfy yourself they will fit over these ferrules which have an external diameter of 0.620"/15.8mm,  If these are just being used for cosmetic purposes (i.e. on a breather or oil pipe that is already a tight fit over the copper oil pipe the pipe is fitted to) - it is possible to just use some form of silicone sealer to hold it in place and then to centre punch the thin walled ferrule where it will not be visible at the rear, to hold it in place to the rubber pipe.

These are far more expensive that commercially available chrome steel ferrules in other sizes - because of the effort and material required to CNC machine them from solid 0.625" round bar stock . . . but add a nice cosmetic touch if you want to fit period black rubber oil or breather pipes - and want to cover twisted lockwire (whcih is the normal method I use for sealing/securing 5/16" bore pipes) or dont like using modern style non-period connectors, which never seem to look right on a classic restoration

Throttle cable adjuster - of the type with tapered top hex, the same as fitted to original Monobloc and 276/289 roadgoing Amal carburettors.

as can be seen from the accompanyning photos, these adjusters look identical in design to the original design - as shown alongside an original Amal Monobloc cable adjuster - with slightly tapered hex top.  This type of adjuster were originally fitted to both Amal Monobloc and earlier 276/289 carbs without locknuts - as the tops for this type were normally threaded.  I believe they were also fitted to later Amal carburettors

Please check the top of your carburettor before ordering though - as some variations of carb tops for these models were made to take a non threaded ferrule - in which case you may want to fit the original design of throttle cable for that type, which normally had an adjuster mid cable.

Final point on these - as sold here, this listing is for the cable adjuster only - normally fitted like this when the top of the carburettor was threaded.  However we also sell the same adjuster complete with locknut - Item 0145 - which is useful if the top of your carb is not threaded, and the locknut can be used to adjust the height.

Pair of plated screws of the type used to secure the throttle cap on later original Amal Concentric carburettors.  Price is per pair of screws. 

These are decent quality crosshead screws that seem to have been standard fitment on later models of Concentric carbs but should fit both Series 6 and Series 9 type.  (I have also seen head screws on earlier models of this carb originally - sorry, we do not sell that type). 

These screws were originally Amal part number 6/086. 

Genuine Amal throttle needle to fit Amal MkII carburettors - original part number 2036/077

We do not normally stock parts for later Amal carburettors - but as this is an alchohol needle for a competition Amal MkII (I believe most commonly used on speedway and grasstrack engines) - it seemed worth stocking.

Genuine Amal item

These Hex type 'Push/Pull' 1/4" BSP thread (into tank) and 1/4" BSP outlet thread petrol taps are of the same general design as fitted to most roadgoing Norton models from the 1930's-50's, i.e. SV, OHV, CS1 and Dominator models.  These particular reproduction fuel taps are CNC manufactured to a higher standard than most others we have seen - and include a gauze filter, and an additional BSP nut and ferrule (whcih means a copper pipe can be soldered in if required). 

Price is per unit

They have an attractive knurl on the 'Push/Pull' buttons, as well as etched writing on the face of the knurled buttons.  The quality of the gauze is very fine and the overall finish of the petrol tap is very good, when compared to other patterns we have seen over the years.

This type of push/pull petrol tap was normal fitment on most Norton roadgoing singles from the 1930's to the 1950's, and they have the correct 1/4" BSP outlet thread - so will fit our period black rubber (ethanol proof) petrol pipe sets as well - Items 0121/0122.

When fitted pre-war - on some models a copper pipe was fitted instead of black rubber pipes - see the left side of the picture taken from the 1937-38 WD16H Spare Parts Catalog to see what one of these original pipe designs looked like - these petrol taps come with an additional 1/4" BSP nut, and a ferrule that lends itself to being bored to fit copper pipe, that can be soft soldered to this ferrule.  (Note: in my own collection, I have an original 1930's twin pipe similar to this - I may consider making a batch of these twin copper/nickel plated fuel pipe assemblies at some time in the future - email on sales@racingvincent.co.uk if interested).

Note - Dowty or fibre washers for sealing to the petrol tank are sold seperately and not included with the taps.

- High quality fuel pipes (modern fuel/emission quality 1/4" pipe - fully Ethanol proof) to give that original black rubber finish of period fuel pipes.

They have all writing removed and are made up with nice quality plated 1/4" BSP unions and crimped ferrules, to give a professional, period finish.

These standard length pipes are of approximately 10" and 10.5" actual pipe length, which gives enough length for nice graceful curves and to fit all the various Norton International and Manx style tanks fitted wth Amal TT/RN or GP carbs.

These pipe sets can also be used with other Norton road models fitted wtih an Amal (or other make of carburettor) - fitted with twin 1/4" BSP banjo fittings.  And of course - the same applies to other marques of motorcycles fitted with Amal carburettors.  However, you might want to check that the lengths stated above are best suited for your bike - we also sell a slightly shorter length of pipes (Item 0122) - or you can email us on sales@racingvincent.co.uk if you want to request a custom length - and we can quote pro-rata (allow up to 3 weeks for custom lengths though.

We use high quality Ethanol proof black rubber style fuel line when making these sets up, and ensure all writing is removed from the pipes - so they give a vintage bike restoration a period finish

Update Oct 2023 Now back in stock - But like everything else, post Covid the cost of these UK manufactured fittings and ethanol proof pipe have risen considerably in the last 18 months - hence the price increase (but which is still less than the % component increase)

- High quality fuel pipes (modern fuel/emission quality 1/4" pipe- fully Ethanol proof) to give that original black rubber finish of period fuel pipes. They have all writing removed and are made up with B.S.P. unions and crimped ferrules, to give a professional finish. - These shorter length pipes are of approx 8.5" and 9" actual pipe length, which should still be enough for most petrol tanks, but can be fitted if you prefer smaller loops with little excess showing. I would suggest getting an old piece of tubing and cutting to this size as a test first if you are unsure.

These slightly shorter length pipes are of approximately 8.5" and 9.0" actual pipe length, which are slightly shorter than our Item 0121 fuel pipe sets - but some people prefer a more direct pipe - and they are also more similar to some road going models fitted with Amal 276 or Monoblock carbs.  If you are not sure what length would suit your bike best - just get a length of thick wire and gently bend it to the correct curve between your petrol tank and carb . . . and then measure that. 

These pipe sets can also be used with other Norton road models fitted wtih an Amal (or other make of carburettor) - fitted with twin 1/4" BSP banjo fittings.  And of course - the same applies to other marques of motorcycles fitted with Amal carburettors.  However, you might want to check that the lengths stated above are best suited for your bike - we also sell a slightly longer length of pipes (Item 0121) - or you can email us on sales@racingvincent.co.uk if you want to request a custom length - and we can quote pro-rata (allow up to 3 weeks for custom lengths though.
