Does anyone have any experience with a walboro 255 lph pump. My question is do you have to install a fuel pressure regulator or does the return line regulate the pressure?

 

Nope, you dont have to have a aftermarket FPR but I would recommend one. Your stock FPR will regulate the pressure unless you replace it with a aftermarket FPR. Aftermarket FPR's are good insurance.

 

What psi is the stock FPR good for? I want to install my 720cc injectors as secondaries, but don't know if I'll need the walboro 255 w/wo aftermarket FPR.

What are the stock fuel line sizes for an '87 TII? What lines do the wlaboro use, or which size fitting should the new FPR have(-6AN or-10AN)??

Please help to clarify.......

 

You just resurrected a year old thread...and then start your own?
I answered in your original thread.
