Re: Fuel Tap

William House
After several years of storage the push/pull petrol tap plunger cork washers of my 1931 Box saloon had crumbled - as described in this forum. I have a new set of cork washers but there seems no way to unscrew the tap plungers to fit them - despite soaking in WD40 and heating. I wonder whether my taps are substitutes which are riveted together with no screw thread? The flat surface of the knurled head has a central nipple which looks like the head of the shaft running right through it. Also the body of the tap plunger is chrome or nickel plated - is that original? Any ideas? Is there a supplier for a new or used pair of taps? I don't have the equipment or skills to convert my taps so they have the original style of screw fitting.


Hello William, assuming that your tap is the same as mine (also on a 1931 Box Saloon) the "central nipple" should have a small screwdriver slot that compresses the cork (or rubber) to make it swell when screwed in an anti-clockwise direction.

This is what it looks like with the O rings in place.

Re: Fuel Tap

There were or are some replacement taps available which were riveted together William. If you drain the tank and let the corks dry out they shrivel up.

Re: Fuel Tap

I have been asked by William House to put on two pictures of the petrol tap valves that he has. As can be seen, these are a riveted type. Is it possible to stretch corks onto these types?

Re: Fuel Tap

I tried the o ring idea,but found the internal holes sheared bits off the rings no matter how lightly I nipped them up.I had more success using nitrile bonded cork 1/8 thick.
For the riveted. Type tap as above many old bike specialist keep them I believe.
Tried punching them out of champagne corks but that didn't work either

That probably explains why my tap has started leaking. Time to look for some corks!

Re: Fuel Tap

I had a look at the LINKS for Seven Workshop and Green Spark Plug Company and couldn't find any cork seals. Can someone narrow it down a bit please?

Re: Fuel Tap

I just bought a pack of 3 cork seals from the Green Spark Plug Company - exactly the right size (about 10mms). I phoned them - a very helpful and real human being answered and did transaction over the phone. She knew their stock very well.

Regarding riveted taps - I will explore some old bike suppliers - thanks to 'Austin in the shed' - which is where mine is at the moment!

Re: Fuel Tap

I've just dismantled my petrol tap, fitted with Viton 'O' rings and find that there are pieces missing as previously described.
New corks on order from The Green Spark Plug Company.

Re: Fuel Tap

Fuel tap corks arrived today from The Green Spark Plug Co. I was worried that they might be too big but they fitted perfectly, and easily with no leaks. I was puzzled why there were three in a set but two are for use and one is spare.

Re: Fuel Tap

Hello David, I did have a quick look at the catalogue but missed the cork seals. I've just had another look and there they are! Sorry, but I'll know where to look next time!
