leaking diesel tank on 36i

[igloo]

have a leak from the top of the fuel tank in stb cabin on igloo - 36i  -  seems to be coming out of the outlet / inlet connections to the tank and appears to have been previously sealed with sikaflex  -   any suggestions as to what would be the best sealant / solution to problem?  tank is nearly full and can see fuel leaking when I 'pump' the tank pushing by hand .  Thanks    John

I used Permatex No. 2 non hardening sealant when I installed the diesel heater pick up and used it to reseal the tank level sensor when I removed it to clean out the tank, no leaks after 12+ months. Because you're sealing between plastic and metal you want something that stays tacky.

I had exactly the same problem on an SO 42 DS. I cleaned the surfaces with acetone to make sure no fuel residue was on the mating surfaces and used a product called "Gasket Goo" that so far has worked ok.
