fuel lab fpr installation

[eoseitz]

I searched on both this site and fuel lab's website but I am still a bit confused on how to set up my new setup. I purchased FIC 650 injectors, racing Technologies fel rail and a fuel lab fpr. I pretty much know how to install the injectors and fuel rail. It pretty straight forward. I believe there are only 6 screws holding the rail on. However, I'm not sure about the pressure regulator. I couldn't pass buying everything for only $400.

From the information I've found on it, there is a nipple for a vacuum hose. Should I t off the port where my waste gate actuator connects or should I use the fuel pressure solenoid line? Right now my boost gauge is connected to my fuel pressure solenoid line. Will I need to keep the solenoid connected since I have an after market regulator? Thanks for any help you can give me.

The fuel rail is held down by 3 lengthy bolts to the head. Then there are 2 small bolts on each end of the rail that hold on the sending line and stock fuel pressure regulator. Straight forward.

For the Fuelab AFPR's vacuum signal, just add another T off the fuel pressure solenoid line. The wastegate doesn't see vacuum and you don't want to interrupt the wastegate's pressure signal, so leave that alone. The rest is self explanatory and you will be able to figure it all out. Best of luck

does the fuel input line go into the bottom or the right hand side of the fpr? I'm assuming one is input and one is output.

The line should run from the end of the fuel rail to one of the side inputs. The bottom hole is for the return line.

my fuel rail has a connector at both ends. I assumed that's where the gas returned to the tank. Does that mean I have to run a whole other return line for the regulator?

Here's a tech article using an Aeromotive, but you should get the gist.

Just take note in the tech article that you WANT to use teflon tape on the NPT side of the fittings (the side that gets threaded into the regulator) but NOT between the AN sections (the other side of the fitting where the hose connects to). Just use a bit of oil on those sides.
