Replacement petrol taps
« on: 28.09. 2018 20:28 »
The 2 taps on my 1969 A7SS seems to be fitted with replacement petrol taps of the push pull type. There are no names on them so I assume they are patterned type.
The taps have always been difficult to pull out and pushed back in.

I removed the taps, removed the plunger retaining screw and withdrew the plunger. I was surprised to find both taps have rubber seals not the cork ones I was expecting. Not only that one of them was breaking up with bits of rubber coming off.

I must admit I have never been a fan of these push pull taps and would like to replace them.with lever types. Does anybody have any experience of replacing petrol taps with quality lever types and can they recommend a pair of suitabl lever taps please? Thanks.

I changed my taps for lever style. Beezermacc, Andrew Guttman, Priory Magneto's supplied them. No problems with them.

 See if that works.

 These are rebuildable if they ever leak. They are nice.

If your fitting the above taps then you will probably need a Bsp Reducer Male 3/8" Male to 1/4" Bsp, available elsewhere but ask who ever you get your taps from

Thanks for that. A guy has given me a link to a set of taps he has whuch he says are good. They have 1/4" BSP thread. I assume they would be the right thread?

 But as mentioned, if your tank is original it will have a 3/8 bsp thread.

 They make an adaptor to go from 3/8 to 1/4.

 If you have a repo tank, the 1/4 will probably fit straight away.

I have tried all sorts of taps with varying success on my bikes but the ones I have settled on are the solid brass taper pet-cock type. There are no cork, rubber, neoprene or viton seals which may be prone to attack from modern fuel and if they do leak in the future you can lap them in with a little fine grinding paste. I bought mine from Feked.
My second choice are the valves used for heating oil, they are available in 1/4" BSP and are cheap as chips and never leak but do not have filter gauze inlets so you will need an in-line filter. OK if you do not mind the colour - they usually have black and yellow plastic levers.

I so agree with you lawnmowerman concerning heating valves.

I have used them on many bikes (except my A for some reason, as her pull-me-push-mes will insist on working).  Even on quite 'posh' ones.
The nasty plastic strip can be hoicked off and slung, and the black paint scraped off to reveal dull grey on the lever. A small bit of stainless or polished ali strip, trimmed to fit the recess where the plastic bit was, can make them look half-decent even. For the square root of diddly-squat £$€, they're pretty unbeatable. Not right, of course not, but certainly fuel-proof, fool-proof and long-lasting, with an easy action.
Adaptors up and down the BSP sizings from 1/8 to 3/8 are easy to get as Lee said, so they really are usable on almost anything - but . . .  only if functionality is the primary objective.
My little bag of Ewart and other corks just sits . . . and sits. Long may it remain unraided.
(The larger 10mm valves make good oil line taps too  . . . yeah, I know  . . . which are also quite easy to rig up to disable the ignition when the valve is closed. Got 4 of them - but not on the A again, as she hasn't dribbled since visiting the urologist.)
