Isspro ev2 fuel pressure ?'s

So I finally got around to installing my isspro ev2 fuel pressure gauge. I'm not to happy with how everything went. First my test port adaptor fitting I got from glow shift leaked diesel soon as I put it on. Should have not gone cheap on the adaptor but how bad could it be? It's just a simple fitting?? So I finally get the gauge in and working and not leaking. Now idling or lightly cruising my fuel pressure is bouncing from 65-68-70-65-68 ect. It's only steady if I stay on it. I'm wondering if I have a bad gauge or sending unit or fuel pump? I changed filters the day I put the gauge in and already did the blue spring on the regulator. Anyone have any ideas?

Mine used to bounce a lot until I went regulated. Now steady as a rock. 55 PSI.

I'm pretty sure they all bounce. My glowshift does the same thing...at first I thought it was the gauge, but near as I can tell they all do it at times. Mine is worst when the engine bogs with the TC locked it'll jump a good bit. At idle or cruising it sits 59-60 and hardly ever moves.

Live with the bounce or put a restrictor between the port and sender, it acts like a snubber. Mine does it but all I care about is that it reads above 45 psi.

Ok thanks guys I was worried I went through all this and it bounces! Feel a little bit better now! Anyone have the Strictly Diesel relocation line? I heard it fits then some say it don't can't find a solid answer. Thanks again!

I run the EV 2 gauges with Stictly Diesel's relocation line it works good although I had to grind the fitting just a little.My fuel gauge bounced with my stock setup and even after I installed my regulated return.Then about 2 weeks ago while on vacation the sensor failed it was just over a year old and they warrentied it with a new updated sensor I haven't installed it yet but hoping it is a little more stable.

What do you mean by that? You just added a regulated return?


Mine bounces also and I have been meaning to find a good fix for it

on my 2nd round of upgrades i did DD's regulated return along with other goodies. I did it despite advise not to. I believe the regulator helps isolate the pulses that cause the gauge to fluctuate. With all my mods the truck runs fantastic. Pulling the toyhauler or cruising the I40 to the river.

My Autometer FP gauge doesn't bounce, but I also have the Strictly Diesel relocation hose that lets you bleed out the air bubble.

Maybe I should have specified that my "digital gauge" bounces. I have never seen an "analog gauge" bounce.


Not sure if that is a trend or just a coincidence
