hey guys, does anyone know what psi the fuel system normally runs at on the v6? also what is the stock psi for the fuel pump as well.

 

I would give airram a call. They offer different psi injectors for the 3.7. They would know

 

Hmm cant help you there, but c'mon give us an update already!

 

FPR sets fuel pressure, injectors have nothing to do with it. They differ in flow rate, not PSI.

 

You should probably go with a Walbro 255 fuel pump, they are fairly inexpensive and regardless of w.e PSI your stock fuel pump is pushing, more than likely it won't be enough for the new set-up, specially if you go with forced induction down the road.

 

Remme reported 56psi.
