Ford Ranger 83 Fuel flow problem.

Hi, I have a 83 Ford ranger that when it runs out of gas the electric fuel pump cavitates and you have to bleed the air out of the system. Well latly the air keeps coming back and It will run for about 1mile then die of no fuel. The tank selector is a 2 position eletrical switch that leads to a solioid I think. after the selector is a electical fuel pump. I can disconnect the line right before the pump and there is no fuel that gravites out of it. If i blow on it, I hear a little gargiling sound then I get some fuel flow but not full. Also when I make sharp turns the pump cavitates for a little bit. Any help with this would be appriciated. TY

Hi Jerdsk8erdude welcome to the forum

I try to follow what you write above but unfortunately I can't get up with anything else other than you have a leak somewhere (and I'm sure you checked that right?)

I'm sure one of our other posters will most probably give you some more expert advise.

Enjoy your stay at the forum

I have repaced the fuel pump and it still dies after about 4-5 miles of driving. I am in the prosses of cleaning the fuel tank. FYI i have 2 fuel tanks.

Maybe something with the ignition not working properly and causing the fuel to spill? (although I have absolutely no idea what)

Check the pickups in the tanks, and make sure there is no cracks in the lines from the tanks to the valve and pump. The smallest crack in that line will allow air to come in and kill the suction. also make sure the tanks vents are open. if the vents are clogged, after a few miles of driving you will build up a vacuum in the tank and it will die.
