hmm ok the sender unit then.. all the lingo is making me dizzy... think i need to lie down;-)
ok my appologies for being sarcastic earlier.. was lookin at sender unit, and typing guage unit ;-)
the sender's o-ring seal was still in great condition, but i think because it is an aftermarket tank the stuff might have been a micro mm out somewhere, and caused it to leak fuel.have added gasket maker to the inside of the seal and on the inside of the sender unit. should be toight now.
so by 2night, 24hrs later the sealant wouldve matured and set nicely.will refit the tank and keep fingers crossed.
tx for the advice and replies.
