I'm about ready to burn this ------- thing

what are specs on a stock 1991 honda civic fuel pump in lph? I stuck a 255lph hp inline in this thing and no matter what I try I cant get proper fuel pressure. Funny thing is is it acually runs good at 80psi :P

I'm going to put a smaller pump in it now after wasting much money on trying to make the 255 work

how come you didnt just use an intank pump? sumped? stock regulator?

stock reg, stock b series reg, accord reg, drilled out reg, now a holley reg(better but not good).

You need a big outlet fuel pressure regulator like I told you, Holmesroller. 94+ LS, perfect choice.

If that doesn't work, drill a tiny hole in the FPR itself. Post pics of one, I'll mspaint where to drill.

Edit: you tried all that? Try running a larger return line, maybe the stocker is too small?

I listened it just didn't work. I even tryed my type r reg off my eg. I drilled out my one so big it takes some real cranking to get it to start, still ---- all. I pulled the line off the reg today and ran a return into a jerry can, that fuel pump puts out like a 3.00 dollar -----. I would swear its much bigger then 255

For whats its worth JD every stock honda regulator I took apart wether it had the big return line or small, d series, b series F series all had the same sized orfice on the inside.

time for an external regulator and possibly a bigger return line.

I made 636 whp Saturday on a Walbro 255 with stock regulator and fuel lines. I KNOW a stock regulator works. Can you think of anything you might have done that would have caused blockage, etc?

pulled the line off and ran it strait into a can, still no dice, maybe a external 255high pressure puts out more Maybe sumping it removed some restrictions in the feed line? I dont know, but theres one bad *** stream coming out the return.
