I have done a l92 head swap on my 00 Silverado and I have swapped out 3 filter/regulators and all have failed,pressure sits at 100+psi can't tell exactly cause fuel pressure gauge only goes to 100 psi.
anyone have luck with other or can give me an aftermarket one that I can manually adjust

 

So you swapped out 3 rail mounted regulators? Same results?

 

Can you explain your fuel system? How it's ran, where the regulator is, where you are reading fuel pressure, etc? Please be as descriptive as possible.

 

Well it's not rail mounted it plugs in to my feed and return line then the front of the filter/regulator plugs onto my rail not sure if you consider that rail mounted

 

It's just a ordinary return system off of any 99-03 truck and I'm reading it off the rail where the male fitting is on the passanger side and regualator is plugged in to my lines where they should connect to my old rail should but since any intake above 04 has only one rail fitting for the line to connect to I have to use this vette regulator/filter

 

See where the filter is in this pic but instead actually plugged into the lines and the rail on a nnbs manifold. That's where I have it pluplugged in sorry i dont have any pics of it actually on the truck

 

Anyone? Any help is much appreciated!

 

I cant see the picture, but do you have it connected backwards?

You can move to aftermarket rails and regulator but it will take some work for it to all fit together.

 

I hate to ask a stupid question but is there any way possible that you have the return and feed lines crossed?
