Fuel leak
1986 F150 4x4 302 EFI AOD
Well, more like a fuel drip from the Y connector hoses on the right frame rail that leads to the vapor canister.

I don't use the empty front 16.5 gal. tank (bad pump inside) and when I fill the rear 19 gal. tank full, I also get leakage from the front tank somewhere on top. Not getting any siphoning to the front tank which is a common problem with this model and went through that about nine years ago replacing the non-electric tank selector/filter assembly, F1TZ-9B263-B.
Any clues on the cause?

After searching the www, I found an answer to my query. The E350 had a similar problem. Seems to be a possible stuck spring or float on the vapor valve top of the fuel tank(s). Hopefully this part is available. Will probably do both tanks and also internal pumps, fuel reservoir/filter, and the OE high pressure pump while I have it all apart. Which brings up another question.
I've never pulled the bed on my truck and will have no help. Plan on using an engine hoist and four chains on the corner tie downs. What all do I need to disconnect besides: battery, six bed bolts, two fender supports, two filler necks, tail light wires? Did I miss anything?
Thanks,
