6th gear

I am trying to peice together a stand alone fuel system for a direct port kit. I do not have 800 bucks to buy one already made. So im throwing one together. My ? is when looking for a fuel pressure regulator what PSI should i look for? 4.5-9/5-10/5-12 ect ect. And what should it be set at for a 200 shot? Thanks for your help?

Flowing psi is going to depend on your jetting.... You can go with a holly blue pump and reg for like 130ish

Thank you sir! This is a learning processes for me, as i have never messed with direct port or a stand alone.

Here is a ruff sketch what i am assuming how a stand alone is plumbed. The fuel cell i am useing is a 3 gal aluminum. It has a -8 an outlet,-8 an return,and a -8 an vent. I am assuming i do not use the return line correct? Also on the other side of the fuel regulator is where i switch over to a -6 an fitting to hook into nitrous solenoid.

No return is called a dead headed system...and will be fine.

As for your fuel pressure regulator, 4.5-9 will be fine (lower pressure uses bigger jet)

One thing I would add is a low fuel pressure cut-off switch (incase the cell goes empty or the pump sucks air)...basic safety

Awsome advise. But what should my MAX and MIN psi be on the cut-off switch?

I "think" they're pre-set to 5psi ? There may be an adjustable one out there ???

Drop Graham a PM...I'm sure he has what you'll need.

Graham@NitrousOutlet

You only need a MIN. It really just depends on the pressure you want to run. I would start at around 10 psi and have the FPSS set at around 7-8psi

They all come adjustable. The way the come as far as PSI setting can vary a little. I would at least verify the setting before ever installing one.

Thanks btw for the referral!

No problem Graham...I'm still learning on this stuff myself and don't want to give someone bad advice and toast their motor....bad enuff if I do my own.

Graham@NitrousOutlet

That was really funny.
