Suggestions for gasket material for fuel change-over tap??

Hi all,

a question for some of you clever people on here...

I suspect the gasket in my fuel change-over tap is responsible for getting me stranded today... not had it apart yet, but it has failed before, and I suspect it's done it again. And yes, I had to get recovered by the Big Yellow Taxi, only the second time in 15 years The Heap has let me down.

It's the same type of tap as the military used on their twin-tank set-up...

The cork gasket apparently has a habit of going hard and shrinking when used with petrol (supposed to be OK with diesel), and subsequently lets in air, so no fuel gets to the carb...

Does anyone have any suggestions for an alternative gasket material that I could cut a new one from? It has to be fuel-proof, easily cuttable, about 3mm thick, and retain some compressibility for sealing when assembled in the switch.

Hope someone can help...

Cheers,

Effortless.

I had the same problem recently on an old motorcycle fuel tap. I used a bit of silicon sheet trimmed from a 'non stick' cookingtray liner. You can often find these in cheap shops like the £1 shop. Assembled with a little grease it worked fine on the bike fuel tap. Can't comment on how long it will last, but being silicon is should survive for a long time.

I made one a few years ago from "Flexoid" Oil Resistant Jointing. I rang someone up and got a sample, can't remeber who though. It worked for at least a year before I sold the S3 109", but I've no idea whether it is working now, and as noted above, you can get the right part number.

Effortless,

Just my opinion, but if you've had the Land Rover for 15 years and probably never changed the tap gasket, I'd have said that the piece of cork has done an excellent job. Just replace it with the genuine article from Blanchards and carry on with another 15 years trouble free motoring from the tap. ;)

Edited: Just noticed, you have done it before. I'll go and stand in the naughty corner. :rolleyes: However, I must admit, I've never had a problem with those gaskets.
