[QUOTE="Strokersace, post: 131681, member: 622"] All good thoughts and options. I actually just crawled back out from under it. Checked all fuses and they're all good. I had bought another Walbro last year when I was having some problems only to find out at the time in was not the pump. So I've had it as a spare in the toolbox. I just installed the new Walbro and with the return dumping into the bucket with no restriction, the pressure at the regulator was easily adjustable up and down. I set it back to 65psi as my previous adjustment attempts had it set at around 45. So I've figured out the supply issue being the Walbro crapping out. The return side still have the issue and it has to be the selector causing the restriction because it doesn't matter which tank I flip to, it's still the same. If it where in one of the lines that was tank specific, it'd only have high pressure on that one. So it's gotta be the selector on the return side. I'm thinking for now, I'll just keep running on the front tank and I'm going to by-pass the return side of the selector. Just tie the return line from the motor directly to that tank. I'll still use the supply thru the selector until I can figure out what I want to do. I called the local salvage yard that I use and they don't have any on the pickups they've got, and I can't imagine those selectors are very cheap through ford. The aftermarket ones I've seen aren't cheap either. What I may end up doing is just tying the tanks together and making them 1 big tank, like the semi's have. I've heard of OBS guys doing this as well but have never really liked how it was done. My just use a sump setup to tie them together, then only pull from one of the tanks. I've got an aux tank in-bed as well, so basically all 3 would be tied together but I could fill them seperately. [/QUOTE]
