Can i use my walbro 255LPH pump and mallory fuel pressure regulator on my gsl-se?

im not sure if the regulator is enought to handle the se's fuel pressure

It should work as long it's a fuel injection regulator.

 

thats the thing, im not sure if it is

 

Do you have part #? Does it say how many adjusted psi's?

This is for carb applications.

This 3-port return-style fuel pressure regulator is designed to regulate fuel pressure between high pressure fuel pumps and carburetors or fuel injection systems. The total adjustable range of the regulator is 3-12 psi. The bypass port sends the excess pressure back to the fuel tank. Returning the fuel back to the tank benefits the pump by running cooler, drawing less current, and always having full volume output available at the desired pressure setting. This style of regulator features a fully machined housing from 6061-T6 billet aluminum, with specially designed high-flow fuel passages. A mounting bracket is provided to allow quick and easy mounting.

 

it says right in there fuel injection systems

 

It's referring to American-style "throttle body" fuel injection (ala Holley Projection), which operates at very low pressures (12-15 psi) vs the high pressure (40+ psi) of bosch style manifold fuel injection. All you need to know is that the regulator operates from 3-15 psi, so it won't work. From the description, it is for retrofitting to a high pressure fuel system, as when replacing EFI with a carb.
