Default High Fuel Pressure Reading

I receive word from this shop that my fuel pressure is reading off the chart like 100 PSI on start up. My ride is a 02 Camaro with a 435ci motor LS7 WCCH All Pro Heads. I made the switch over to E85 and brought everything that is need for this E85 fuel like new connection wire plus this kit ( http://walbrofuelpumps.com/450lph-wa...f90000267.html ). The shop mention that when you fire up the ride,fuel just spit all over place from my injector dynamic injectors. What can cause this issue and how can it be solve.

They put in new fuel pressure regulator and that didn't work to control this high fuel pressure.

Answered your email.
Seems like you need to get a lay of the land first, see what exactly was done, and then either check yourself or have someone else you trust check it.

If shop B (?) Installed a new fpr was it external? If so they likely did not remove the internal fpr from the tank.

Its also very likely the internal fuel pump tube inside tank is kinked.

Lots of options.

Sounds like someone fucked up the install.

So give us some details on what has been done etc etc ? Is this a new fuel system ? Installed by a competent person ?

Full details.

And even 100psi would not cause the injectors to leak fuel...unless of course they too have not been installed correctly.

where are they reading fuel pressure at? Hopefully itís downstream of the regulator! It sounds like theyíre either reading fuel pressure UPSTREAM of the regulator or they donít understand how to set the regulator. Either way I would be looking for a new shop personally.
