I've been getting fuel in the bilge when I overfill the tank and have avoided it by filling up to 85l instead of the full 90 until I get around to properly sealing the fuel intake hose where it connects to the tank and fuel sender thread which I am finally going to do.

Being a poly tank I know I should be using a non hardening sealant so is this the product I should be looking at or is there something else that is more applicable to what I need it for? Cheers
