Question Fuel Pressure Guage

I'm looking for a guage but keep coming up with only 0-15 and 0-100 psi guages. I would think that you wouldn't want one with 0-15 psi because it would be pegged half the time and the 0-100 psi wouldn't be accurate enough. But I see that you guy's are talking about a 0-30psi, where can I find this? Secondly and PLEASE forgive my ingorance but when you fellas are hooking these up your not accuataly running the fuel into the truck are you. There must be somekind of isolator or will the electric's hold up? Thanks Fellas

Check out ROD at Wildcatdiesel.com I just bought a set of gauges from him. There are lots of threads on this subject. I was pretty ignorant also prior to reading all the stuff thats out there. Pd about $350.00 for three gauges, pyro, fuel pressure, and boost. Got all the hardware needed to install + a pillar mount panel.

Yes, I will be running fuel into my cab...Alot of guys state that they have never had a problem....read on my friend.

Thanks I will have to check in to Wildcat. Kinda dangerous isn't it in case of accident and fire to have fuel in the cab though huh, or does the pump shut down like in ford's in an accident.

Look at guages designed for diesel applications.....autometers are not.

Look at Isspro (Rod will agree) or diPricol. They are available in the correct ranges and are designed to be used in diesel applications.

There is a huge difference between gasoline & diesel fuel.
As you have stated, "In case of an accident....."
If you throw a lighted match in a bucket of diesel, you'll have a cold, wet match.
Diesel is much harder to ignite than gasoline.
3+ years, no drips, no runs, no errors.
Mechanical gauge on top of the dash.

Hey Shoverlhead thats a great pic, Thanks. I was actually pondering doing what you did and wondered how it would look compared to the dash pod that autometer sells. I think i'll do what you did. I really like the fact that they are all full sweep guages and not just the top half, much more accurate and easy to judge. So who makes those guages?? Thanks again to you Shovelhead and everybody that takes time to educate me. Corey

Those are Isspro EV series gauges.
L to R - EGT(pyro), Boost, Auto Trans Temp, Fuel Pressure (mechanical).
The whole set-up came from www.wildcatdiesel.com

I was running into the same problem I had a EV pyro gauge mounted and wanted boost abd Fuel pressure. I do not want to run fuel inside the truck period. I play the bucket of diesel trick on guys all the time so I realize that it is not volatile in liquid form. I couldn't find a gauge to match my other two Ev guages, so I went to the X-monitor very accurate you get readings in 10ths also and the truck looks very stock inside also. Bit more expensive but I think worth the dollars. The upside is it will play back all the readings during a run and warn you buy flashing when a limit is passed. You can purchase them at most diesel shops but talk to BD they make them.

www.genosgarage.com is another option for you. The Westach is an electric guage and can be purchased in kit form if you wish.

say when istalling the fuel pressure guage, what are you guys putting on the threads to prevent leaks? I was told for some reason and don't know why but, you shouldn't use teflon tape, yes/no? Thanks fellas

I used Pipe-Dope, but only on the NPT threads.
You don't need to put anything on AN fittings, they're designed to be self sealing.
Teflon tape is a no-no as even the tinyest thread of it could find it's way into the VP injection pump with expen$ive results.

Definite no no for the teflon thread tape....

Use liquid teflon instead - Loctite 567 PST Thread Sealant. This stuff works great and is available in small tubes....the 6 mL size will be all you'll need. You should be able to find it at any industrial supplier.


You can look it up here (under thread sealants):

Permatex #2 works well. Isspro Marine 0-30psi gauge w/6ft SS braided hose. I figure if its good enough for marine use shouldn't be a problem in the cab. Gauge in cubbyhole. Who needs an isolator anyhow. Do have needle valve shutoff on bottom of fuel filter tho. Go whole setup from Rod at www.wildcatdiesel.com for about $100 or so. But that was sometime back. Don't know what current price it. Give him a call.

I agree totally. For quite some time I was hesitant about running fuel into the cab but if you use good quality parts and install it correctly you wont ever have anything to worry about. The isolators cause more problems than they are worth...
