Pump not drawing fuel
Ok so my son and I are new to this whole truck restoration thing, but we're eager to both learn. We recently scored a 77 F250 camper special that's sat for about 14 years. When we bought it it was running. The previous owner had done quite a bit to clean it up. When we got it to the house we drove it around a bit for fun, and parked it until we could drop the tanks to clean them out. That's done, we've replaced the fuel sensors in both tanks, the lines are clear based on us blowing air through them from the engine side back to the tank side before connecting to the tanks. The mech. fuel pump is brand new and seems to have suction when we turn the truck over. We've installed a fuel filter before the pump in an effort to filter any possible residual junk out of the lines, but we can't get fuel to the engine! (Yes we put gas in both tanks.) The truck will run when we run a line Direct from the pump to the a gas can, but not when connected to the tanks. What could we be missing?

Did you change the rubber parts of the old fuel lines when you did the rest? Sounds like you could be sucking air between the tanks and the pump. Where it is both tanks I'd guess it would be the switch or after the switch. Maybe one of you could put a little air thru the lines from just before the fuel pump, (tank side)while the other crawls around listening for a leak.
