You really need a fuel pressure gauge on that truck. I would upgrade the fuel pump before adding any injectors..... atleast a holley blue pusher. They are good pumps & cheap upgrade.

I second that. A fuel pressure gauge is cheap compared to a VP44.

Get a gauge and swap or add a pump. Then your good to go.

If the OEM pump is in good working order it will be enough pump..... But until a pressure gauge is hooked up to evrify its health its anyone guess. The OEM LP is very unreliable. There are several good alternatives that have proven to be reliable with good life expectancy.

I ran 100Hp injectors and with my comp turned up I could make the fuel pressure go to zero. Get a gage!!

as you can see from my mods im still running a stock lift pump, but thats about the only part in the system thats still stock. I idle at 14 and never drop below 12 at wot. The draw straw was what made the diff in the pressure drop not being as large when on the skinny pedal. As soon as money provides i will be going fass or airdog, not so much for the pump as i want the 3 micron filtering.

most of the gauges for fuel pressure that i have seen or used on other applications have been unrealiable and bounce around quite a bit so i have shyed away from purchasing another but for now I am installing a low pressure light set to come on around 5 pounds. went to my local diesel performace shop and set up to have a dyno run before i do the injectors still deciding on what ones to go with its between the 110hp and the 130hp leaning toward the 110's since i have stock turbo and don't know when or if i will up grade turbo

At least move the stock pump to the frame rail and get a gauge. My mechanical gauge does not bounce around. It is a Di Pricol with isolator. Has work great.



I picked up a couple lbs at idle and about 5lbs at WOT by moving the pump, and I already had Geno's bango's.



BTW, I used Geno's kit to relocate my pump.

My gauge doesn't bounce at all. The vulcan big line kit mad a big differince . Still need to move it back to frame rail.

I am running Mach 4's and all I have is a stock pump down by the tank with -6an lines. I can pull my press down to about 6 but it recovers quickly. Still on my orig VP44 and truck runs good. I am going to add a system from Glacier Diesel this summer, just for piece of mind.
