Would connecting a fuel solenid to the return port of a fpr Teed into the fuel line going from the fuel filter to the rail let me regulate pressure to the solenoid?

 

Nope, you have to use the fpr outlet instead of the return. Place a T in the fuel line and run a line from the T to the secondary fpr. Run a return line from the fpr return port to the stock return line and T those together. Then run a line from the outlet port if the secondary fpr to the fuel noid.
Another option is to use a returnless fpr as your secondary fpr. http://www.aeromotiveinc.com/p...ators 13105 should do the trick. Just run a line from the stock fuel line to the fpr inlet and a line from the fpr outlet to the noid. I don't believe that the fuel pressure should change since you'll be at WOT when ever that fpr is in effect. You'll want to look into this just to make sure.

 

Here is what aeromotive said to me:
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by aeromotiveTECH &raquo;</TD></TR><TR><TD CLASS="quote">I understand what you need, and the answer is no. Bottom line, your fuel pump is putting out pressure, just flow volume. The pressure in a bypass or return line system is created and maintained by the regulator, specifically between the regulator inlet and the fuel pump outlet. When you turn on the pump, fuel is trapped between the pump outlet and the regulator inlet, held there UNTILL the pressure reaches the set point, then the regulator effectively leaks volume, via the return line, in a fast enough rate that the pressure cannot go higher than the set point. If you install two regulators on the same pump, and attempt to set them to two different pressures, the regulator that is set for the lower pressure
will become the default regulator, opening at the lower pressure and leaking enough fuel that there is no higher pressure in the system. In effect, the regulator set for the higher pressure would in fact, never open on the bypass, because it's set pressure would never be achieved. To do what you want, you need a dedicated, one gallon fuel cell, with a small pump like the Aeromotive 11106 and dedicated regulator 13109 (if you're running 30-70 psi on the nitrous) or 13204 (if you're running 5-15 psi on the nitrous). This is the only way to create a second, different pressure for your nitrous system.
Sorry, I know that's not what you wanted to hear, but it is the way things work. Good luck and thanks for choosing Aeromotive!

Well damn, guess I was wrong on that one. Good info though.
