Angry Fuel line diagram???

Does anyone have a diagram of the fuel lines for an '87 f-350?

I replaced the injector caps, o-rings, return lines between injectors and the return line going back to the fuel tank selector switch, even the "olives" that seal the fuel header to the injector pump.

After replacing all these lines the truck starts fine after I prime the system, but if I let it sit a day or 2 it will start right up on the first revolution, run for about a minute then run out of fuel.
I then have to bleed out all the air that has entered the system from only god knows where and try not to kill my batteries or starter in the process...

This is driving me MAD!!!

Is there a check valve somewhere that might possibly be missing???

I don't want any bypass or electric fuel pump quick fixes, I just wanna get this issue resolved once and for all...

Thanx

For $30, replace the fuel pump, nothing will last forever.
How old is your current fuel pump?
