Fuel Resistant Gasket/Sealer ?

[GordonC]

I'm looking for some advice if anyone can help, I'm puting a glass panel in the side of my aluminium fuel tank on my racing buggy so I can see how much fuel is in the tank as its not possible to look in the filler cap to see. So I'm looking for a rubber gasket or sealant thats fuel ressistant to seal the panel with but I cant really seem to find what I'm looking for. Does anyone have any ideas ? My dad said he used stuff years ago for fuel tanks, it was like putty that you moulded into shape and it set like rubber but I cant find anything like that anywhere

Thanks,

It was called "petro patch"
Be better with a couple of elbows and a bit clear fuel pipe
like a sight glass

I have used something similar to petro patch to re seal the petcock on my fathers bike tank as nothing else worked on it. worked well and still going strong a few years later, although I agree with doubleboost, an elbow out of the bottom and a length of clear pipe up the side of the tank would be better, unless it poses a risk to being broken and spilling fuel everywhere

Or use a dipstick attached to the filler cap?

Or use a dipstick attached to the filler cap?

surely fuel wouldn't show on it? Just run off when you pull it out. Ive never tried a dipstick in a fuel cell so don't know

We have dip sticks on the petrol storage tanks at work
Use brass dip sticks to avoid sparks

Wooden dipstick, works a treat. Ie wooden brush handle.
