cheap source for fuel pump, and which one do i need?

Hey guys. I'm showing 35 ibs at the engine fuel rail, 45 without the vac line on the pressure regulator.

I'm pretty sure 65 is normal if not optimal, and therefore the injectors aren't atomizing the fuel correctly.

Does anyone know where I can find a fuel pump for a low price. Also, Autozone is showing two different kinds. My Jeep is a '93 2.5. Which one do I need?

Really? Well crap I thought it was supposed to be higher, around 65. Is there an online manual to reference? Thanks.

The Haynes manual lists the correct fuel pressure as 31-35 psi....
