Will it work? Dont know if anyone has tried this, but here goes:

1-3 gal custom fuel cell with baffling and intank (or inline) Walbro 255L pump in a -6 feed line with filter, a return style regulator set 58psi, -4 return line, into the fuel solenoid feeding a direct port nitrous setup and an electrical FP Gauge. Not sure on how the regulator will work, Guess if it see's the pressure from a closed Fuel noid it should just recycle the race gas back to the cell right?
Why use a hi-pressure? *****-n-giggles Figure I could mount the cell either in the front bumper area, battery area or in the rear area, not sure what is NHRA Legal so researching that side. But will this work with the regulator setup like that? And has anyone used a hi-pressure system like this?

I am also wondering about a high pressure standalone system. I don't think they would be as sensitive to pressure changes as a low pressure system.

I was thinking the same thing only using the stock pump I took out of my car. I am looking at using the same aeromotive regulator I have on my main system. I was going to set it at 43psi. Then when tuning I can adjust the fuel pressure to change A/F instaed of changing jets for small adjustments. I hear people talk about being in between fuel jet sizes. Figure it will make life simpler with the direct port.

That is very close to the setup I have. I am running around 60 psi for a TNT which requires it. The cell is located where my coolant resivoir was. Here I believe these are the parts you need:

low pressure is easier and you don't even need a regulator.

most people with low pressure setup's flow test them before each run of at least each once a day they use them. High pressure would not be as sensitive to pressure changes.

Most people? never heard of that one.
IMO they are the simplest thing going, and no maintanence.
Once I saw what the pressure was on mine, I never needed to use the gauge again, or even a regulator... pretty simple.
Maybe you've just talked to a lot of people who make fuel systems more complicated than they need to be.
With a separate fuel cell and no regulator, there's nothing that could change the fuel pressure from run to run except for voltage. Keep that a constant and you'll have your consistency.

To try and erase any misunderstanding out there, you can run whatever fuel pressure your system gives you. You just jet your fuel side to get your desired AFR while it's in operation.

white2001s10- after knowing some ppl using a low psi setup, the traditional holley blue/red pump etc, I have seen the need for the system to purge the line of air for the fuel or whatever you want to call it. And pressure changes as well is a benefit.
Ray had to go and be a blabber mouth, talking about using an adjustable reg, pill it like it was a mustang (43psi) and then adjust the reg for a little finer tune. Great, let all my CATs out of the bag.
ibenrg- Thans for the post, how well has your setup performed? Any issues and do you adjust the psi for fine tuning?

yes I have seen that myself many times from people who use THOSE pumps with a regulator. I would never use those pumps myself... ever.
I prefer Carter pumps with no regulator.

The setup works great. The pressure drops about 2 psi (from 60 to 58) when I hit the kit but that is without using the vacuum on the regulator. Yes, you tune the car N/A with the computer and then tune the car on nitrous using the regulator. Once the regulator is set, no other adjustments are needed unless you change your car. FYI, this is on a TNT F2 kit with 150 shot jets and 107 fuel...

I am looking at a custom NX DP pilled for in excess of 300shot. Thats another need for the high psi, using only 2 solenoids it can only go to 300-350 max, and any deviation in the low psi pressure will have a more devastating effect, or so I would think. Using the hi psi, I can run more hp jetting, and again have the adjustments on the regulator. I see what your saying now about the style and brand pumps, never thought much about that aspect, white2001s10 (BTW, whats your name?).
