Is there any gasket compund which will not be attacked by petrol? I've got a small leak on the pump flange which will not seal with the naked gasket and needs a little help.

Yes, I bought some to seal my tank sender and didn't end up using it.

It's in a tube and looks just like your normal blue gasket compound, but says "Safe For All Fuels" on the front. Can't remember the make but I bought it from my local motor factors so it's not a specialist product.

Tiger Seal is meant to be petrol proof according to Practical Classics (I think it was).

That's the second time I've heard that Tigerseal can do the job - but surely it will make the joint very hard to break if required in the future.

I was really hoping to find a proper gasket compound for the job, but thanks for the tip.

I'll have another trawl round the moterspares places tomorrow.

The good old standby, RED HERMATITE, will seal almost anything, and its non hardening. Been around for many years, forty to my knowledge, so must have something going for it. I personaly wouldnt use anything else. HTH Ray

Im almost certain my old neighbour used the red stuff for his fuel tank. Only problem was that when 2 bits were bolted together it squeezed inside which left a thin section. This eventually broke off in pieces and blocked his pump / filters etc. Maybe he used too much??

As above - motor factors should stock various stuff that will be fuel resisitant.
