ok i have a cammed ls3 with vic jr and 4150 TB setup, im going to run a 200 shot direct port. running the holley 12-1400 pump with -8 lines and holley reg for fuel, im just going to T off for my fuel solenoids. will this be ok??
do i need a separate regulator for the solenoids?? or will my pump and reg be ok>??

pics of direct ports is appreciated so i can see the way yeverybody else is plumbing theres


Thanks

You've got enough pump but I would recommend a regulator just for the nitrous side. You will have more adjust-ability on the fuel side that way.

do you ha ve a diagrma on how i would run the lines?? which regulator?

best way to do that is to run a fuel log. magna fuel, jegs, summit will all carry them. You run a regulator for the motor and one for the nitrous. On a low pressure tune up the little polished holley regulators work great.

ok, so Y the main fuel feed line, one go to the rails and one to the pressure regulator for the nitrous. and then out the other side of the regulator to the fuel solenoids? and just plug the bottom/ return part of the reg?? i understand having a reg for the nitrous im just confused on the plumbing

Don't plug the return. You will need to run that back to the tank.

What regulators do you have?

I second the request for a drawing. For me, the first regulator is a rail mounted OEM LS1 / Bosch style from the 97 Corvettes, the second, Aeromotive's p/n 13301 (3-65psi universal).

I'd really like to set this up, but always thought running two regulators wouldn't work. My assumption was if the OEM regulator is set to 58 psi and the nitrous system's regulator to ~6 psi, then the return port on the nitrous system's regulator would regulate the entire fuel system down to ~6 psi and starve the injectors. The OEM regulator would never see anything near 58 psi...

I never thought of blocking the return port on the nitrous system's regulator... right now, that seems like it would work because the fuel that would otherwise be returned directly to the fuel tank (via nitrous system's regulator) gets "returned" to the fuel rails leaving the remaining pressure regulation up to the OEM regulator.

here is one I had made for a carb setup...uses 1 return regulator and 2 dead head

if running a low pressure (nitrous) and high pressure efi...you could run the nitrous FPR off the return line going back to the tank...but you need to make sure the pump is moving enough volume to support both
