22RE fuel pump pressure?

[minitrucker]

So i bought myself an aftermarket Fuel cell, i'v already replaced the GM sending unit. I don't want an internal fuel pump but since its EFI I need to know the Pressure so I can swap it out.
Does anyone know what it is? Or how to find it?

any help would be much appreciated.

Thanks

nevermind i found it after a while of digging around. For those of you that don't know its

"Fuel pressure
Fuel pressure plays a big role in the operation of a fuel injection system. Because the injector is essentially a gate valve for fuel delivery, increasing fuel pressure can allow you to cram more fuel into the intake tract for a given injector pulse width. Typical fuel pressure for a stock 22RTE engine is 43 psi. The maximum fuel pressure that the stock injectors can handle is about 70 psi -- above that and the injector begins to fight the fuel pressure to get its valve open, and fuel deliver actually decreases in volume.

Fuel pressure is determined by both the fuel pump and the fuel pressure regulator. The stock fuel pressure regulator has a hose that connects it to intake manifold vacuum/pressure, so that as manifold pressure rises, fuel pressure also rises, typically by a 1:1 ratio. The pump determines the overall volume of fuel that the system is capable of delivering to the injectors. The size of the fuel lines can also be a limiting factor if fuel demand is significantly greater than stock."

Good to know, thanks.
