1PDQ55

I just read one of the other threads about a strong gas smell when the tank is full, but mine is pretty strong and I crawled up under there tonight. I'm under 1/4 of a tank and there in no smell now (seems to only be when above 1/2), but there are signs of it leaking at one time or another. It looks like maybe someone has done a patch job on the pickup in the past. Do you guys know if anyone makes a repop fuel pickup or at least gasket?
