walbro 255/Kirban FPR?
Ok so this is the deal... I installed a walbro 255 in tank pump in my 85 Iroc, and I have it ran to my Kirban FPR which is feeding my 383 HSR, Im using Holley HP efi. The problem is I cant get fuel to go through the kirban and into the rails. I actually heeled the regulator in my hand and primed the fuel pump with the gas line hooked up and nothing came out the other end. So I turned the adjuster screw both ways and nothing. At this point I just took the regulator apart hoping to find something blocking the passage, nope. Then I decided to put the Holley regulator on that came with my HSR and the same thing happened, nothing. Why am I getting fuel to the regulators but not fuel through them? After 13 hours of working on my car yesterday I never got it started, This build has been taking place for four years now and I really thought I was going to hear it run. Any help would be appreciated. Thanks.

Re: walbro 255/Kirban FPR?
Is it possible that Im not getting enough fuel pressure for the regulators to even work? I know I have some pressure because when I disconnect the fuel line from the regulator it squirts everywhere, I have to lay paper towel down and cuff the fittings untill it bleeds out. Nobody has any ideas to what is going on?

Someone please. Can anyone verify what the line pressure should be before the regulator using a walbro 255?

The same as after the regulator, if it's a return-type reg.
I have no idea what the pump is capable of producing if dead-headed. But, it should be well over 60 psi.
