1994 Ford F-350 Question: air in fuel system

Truck stalled several times. Fuel filter was changed then truck started and died a few times then would not start. Filled filter with fuel and engine started, ran for 15 minutes and died and had to purge fuel system again. This is a 7.3 L Turbo Diesel. how would air be getting in fuel system? does this truck have in tank fuel pumps? -
Answer 1
This happened to me. If its been setting for long periods without being run, algae builds up in the diesel fuel in the tank and gets sucked up the fuel line causing it to stall. I eventually found some additive from a marine shop and added the initial dosage and let it set for a week. Each time I add fuel I put it in and it works great. Just don't let it set for weeks (months) with out being run. I have two tanks and alternate between them to keep any from getting old. -

Change your mechanical fuel pump, even my brand new pump was faulty i had this problem for 6 months and founf the fuel pump check valve was sucking air -

Hown do I bleed air from the fuel system on a 1996 ford f350 7.3 power stroke turbo diesel? I just changed the fuel filter. -

there should be a bleeder on the fuel filter housing -
Answer 3
Check the fuel pump check valve. If it stuck in the open position you will continually get air in the fuel system. Fuel pump is in the tank I believe on that model. -
