Fuel Cell Set-Up Help

[speedyangie]

I have a new fuel cell mounted up in the RZR and was wondering what people are using for a fuel pump, regulator, etc. Need help with the set-up. View attachment 8206

aeromotive regulator, MSD pump, pre and post filters any brand. i used generic Chevy threaded ones.

 

[speedyangie]

What psi does your MSD pump out?

 

[speedyangie]

I have a BDL regulator and a Bosch pump, but I think the pump is pumping too much fuel or the regulator isn't regulating it.

Do you have a pressure gauge on or inline with the regulator? Is your regulator adjustable? EFI generally runs in the 45 to 55 psi range.

 

[speedyangie]

Yes, pressure gauge on the regulator. Regulator is adjustable...checked pressure going to fuel rail and it's at 70 psi after changing to a new pump rated at 45-65 psi. Maybe regulator is bad? Trying new regulator today.

 

[speedyangie]

Am I missing something? Breather? Filter? Return? What's the set-up supposed to be?

 

[megadesertdiesel]

The aeromotive regulator I used had 5 ports. Out and 4 return locations. I just blocked off the 3 returns I did not need. I ran 40 psi to a r1 engine.

You need supply to fuel rail, return to tank, and vent from tank to high on rollcage with a 360* loop.

 

[speedyangie]

Okay. The regulator I have has three ports and a spot for a fuel pressure gauge. I have a gauge on there, one port that's being fed from the pump, one return to the block and one blocked off. I have a hose venting from the fuel cell that I'll run up...and as you said 360*.

I'm getting a different reading from my pressure gauge on the regulator and a gauge that I have directly on the fuel rail.

Are all your fuel lines the same size? Sounds like maybe the pump is running inconsistently or you have a bad regulator.

 

[speedyangie]

I think we have it figured out. First we were running too crazy of a pump. That ruined our regulator even after changing the pump. So, after changing the pump to one rated at 45 psi and putting in a new regulator. We're golden!

 

[speedyangie]

Thanks for everyone's input! Time for bed, racing in the a.m.

Fuel cell worked View attachment 8216

 

[speedyangie]

So, it worked but didn't work at the same time. I keep ruining my fuel pump. Ideas?

My set-up is - fuel cell, fuel pump to fuel regulator (two port in/out and return).

What's the problem?

 

[speedyangie]

Do I need a return system? If so, how is yours hooked up?

 

[BiggJim]

I am not sure if the S model has a return, but the xp does, its on the other side of the fuel rail, just route it back to the tank.

do you have a pic of the stock tanks pickup/pump setup? good thing about a fuel safe is the large oval steel center plate. after many headaches on 4 cylinder ford rangers i just mounted the stock pump/pickup/sending unit in the oval plate and called it a day.
