Having ballsed up cutting the hole for the sender in my tank I have to seal the spare 2" diameter hole in the top!

Not having easy access to a TIG set right now I just want to cover the hole.

I've made a disc up to do it but I need some gasket compound that's petrol resistant.

I've seen Hermetite Red at Halfords but it just says petrol resistant. I want something that will definately survive petrol long-term.

Any ideas? Or is the Hermetite Red fine for this?

Thanks,
James

Cant you get a petrol tank repair compound that comes in a stick still. Ive used it before. Im sure you can work it in your hands to soften it up (just like plastercine). Im wondering if this will then act as a seal??
It was in a cylindrical pot, roughly 1" dia, 3 or 4" long. Only a couple of quid. Granvilles rings a bell as the make.

I used it on an old cars tank that had a slight leak around one of the pipes. Worked a treat.

I seem to remember my neighbour used the red stuff on his vintage car to seal the sender in, it squished inside when tightened down and then broke free when it cured and worked its way partially up the fuel feed to the carb. I dont think it 'melted' as such but had a similar effect as dropping a plastic bag in your tank - ie car will always run fine when your mates are standing round trying to help but when you are poshed up taking wife out it will break down just as it starts raining.

Frost automotive?

You can use epoxy.

the sender on series land rover is fitted on top of a cork gasket using 6 small screws.

if it was me, I'd use some gasket material under the disc instead of cork; you can buy it is sheet form and cut to size.

Got a large supply of stuff called PRC, use it for fuel tank repairs on the RAF jets (the RAF use it to stick almost everything together)

Great stuff, but bloody stinks. U2U me if your interested and I'll bung some in the post.

I used red hermetite to seal my fuel sender and had no leaks, however when I removed the inline filter recently I found a lot of hermetite particles inside it.It hadent dissolved but appeared to be bits that had broke off from the inside of the gasket and bolt holes.
