I bought an 87 toyota pickup with a 95 V6 4.3L Vortec. I installed an inline fuel pump which had a max output of 60psi. around 3 months later the inline pump sounded like it was cavitating air and then it didnt have enough pressure to drive the car. so i pulled the pump and primed it, installed it, primed it with the ignition and then it ran fine. 5 minutes of driving after that and then i had the same problem again. i checked all of the fuel lines for leaks and couldnt find any. i then bought a new inline pump, but it only has a max output of 55psi. the engine wont even fire with it. with the old inline pump, if i primed it with the ignition enough, the engine would at least start up.
The Chilton's GM S10/Sonoma Pickups 94-97 repair manual states that for a 95 vin W, the engine needs 58-64 psi. Baxters autoparts is where i bought the last inline pump and the guy there was definately sure that it needed below 50.

If this has cpfi Vortec the specs are 55-64, get a GM pump and be done with it.

Would i be asking for an inline or an in tank pump? Do i need to buy it from GM?

I just figured out that my problem was that I used the wrong type of rubber hose. This was causing the hose to collapse on itself. For a pickup tube in the gas tank, to replace the in-tank pump I used a generic rubber hose instead of a fuel hose. After I replaced it with a fuel line the engine fired up.

I know that I still need a fuel pump with higher pressure.
