What fuel pressure do you run if you have a gauge?

DTT Assassin FTW!

Most are moving over to the belt driven pumps.

From there site...

DTT Billet Assassin Fuel System is the most reliable fuel system on the market, its also very easy to install and maintain. Most customers love the fact that is also doesn't make noise like the electric fuel systems. At DTT we build everything from scratch, so that we have complete quality control, and any necessary replacement parts.

Kit comes complete, with all necessary lines and fittings for installation. Kit also includes a drawstraw, pulleys, belt, drive bub, and bolts for install.

This pump is like a work of art when you see it.

I'm glad I ordered it when it was still $485.00.$585 woulda been steep. But they gotta make money on it. . .

So just a quick question for anybody on this thread. Where did you all tap the fuel pressure gauge into? I dont have one yet:banghead:, but am looking into getting one very soon. Also, what is bad about the FASS DDRP pump? Im just curious....

[Rogan]

there's a fitting on the VP pump to test fuel pressure.. I replaced that banjo fitting with one designed to hold a FP sensor.

I went with the DDRP & 3/8 big line kit a year ago and no problem yet ,running roughly 18 psi idle and 14 psi WOT,kept the original OEM filter & drawsraw.It's a pretty good set up,I 'm not planning any mods,my gauge hose is set up on a T before the VIP,with the big line kit it makes it easy as everything is JIC fittings.

[Ilikeoldfords]

Ok cool. My truck came with the ddrp when I bought it. Another question. What brand of fuel pressure gauges do you recommend? I'm looking for something fairly cheap but accurate of course:)

[wagntagn]

I'm using a liquid filled gauge on a 1/16 ID hose,I leave the set up under the hood,once in a while I pull the set up on top of the hood to see my pressure.Eventually I'll set up a pillar gauge.

[Ilikeoldfords]

Ok. any suggestions on a brand? I will probably want a 0-30 psi gauge. How does everyone feel about a glowshift? Found some good deals from them.

[Mopar1973Man]

Glowshift is considered to be a low quality gauge by some. But if you get a mechanical gauge and needle valve you'd be all set. But I don't think you can beat a $40 buck ISSPro gauge...

Awesome, thanks mike. The reason I was looking at glowshift is so I could ge a package deal and have all matching gauges. I will probably get the isspro one for now though.

[Texas CTD]

Check out Vulcan Performance or Diesel Auto Power. Isspro gauge packages for $309.

I second isspro, have installed several and they are top notch. I run isspro egt, boost and trans temp.

[Ilikeoldfords]

So i got an Isspro 30psi gauge. The one I got didnt come with any plumbing or anything to hook it up. Now how do i go about hooking it up? I have heard about using a snubber or an isolator but where does that get installed? Any info would be great. I just dont know what the best/easiest way to go about it would be. Thank you everyone!!!

Thanks. I should have looked harder :banghead:

So mike, you are just using that needle valve? does that take place of the snubber then?

[Texas CTD]

Yes it does. It works better than a snubber. I'm using one too.

Another added benefit to using the valve. My gauge line developed a leak and its been way to cold to do anything with it outside, so i just shut the valve off and waiting for a warmer day. Sent from my DROID BIONIC using Tapatalk 2

Ya I have decided to run a valve instead too. I have all the stuff and I'm gonna hook the gauge up tomorrow. I gotta get the valve in the morning though.

[Ilikeoldfords]

Got my gauge all set up. Runnin a solid 15 psi at idle. Hung around 13 while cruising. Did one hard pull at wide open throttle and it dropped down to 9 for a second. Is this about right for a ddrp?

[fire176969]

That's low. Anything below 10 is causing damage to the vp44 and below 14 will cause the overflow valve to close and could cause the ecm to overheat on the vpSent from my DROID BIONIC using Tapatalk 2
