the engine died it ran out of fuel, the fuel pressure gauge went to o, i pushed it to the station and filled it up it took 23 gallons, had to jump the fuel pump relay and reprime the system, fired right up ,
the tank doesnt appear its ever been out of the truck, its the long tank for 34...
i have a 94 k3500 crew cab long bed, it has the 34 gallon tank in it
when i fill the tank completely up and drive till it runs out of fuel, it took 23 gallons to fill the tank,
what might cause this, i would like to be able to use all the 34 gallons if need be
installed fuel pressure gauge today,,,
6 psi idleing at 1200 rpm
4 psi cruising 55 in 5th gear
1 psi hard aceleration in 3rd or 4th gear,,,
at 35 mph in 4th gear in town the motor accelerates easily, doesnt seemed lugged down at all
are these pressures good , bad, or ? never had the tank...
