leaking fuel sender

[Del1968 18]

hi all 

filled the car up the other day and fuel spilled onto the floor of the garage thoght it was coming from the rtn pipe on the fuel sender which is the sierra one the rtn is being used as a breather which is higher than the tank but when i took the boot floor out to check there was fuel all round the sender so looks like i will need to remove and clean up and reseal what is the best sealent to use and where to buy from online 

cheers del

Cork gasket should be all you need.

I used a cork gasket which I made from a sheet of cork I bought from ebay, I put a very thin layer of blue Hylomar to seal the gasket-don't put any sealer thick enough to squeeze out of the join as it will react with the petrol . Another thing to watch is not to over tighten the three studs as this can distort the thin top of the tank. I did mine 5 years ago and have had no problems since.

I used two metal bars to bridge the studs as just bolting up the studs caused the tank to bend. I used oil filter seals and a cork layer.

A ring of steel would probably be even better
