this mechanical gauge was 42 bucks. less than 1/3rd of an electrical gauge. i'll take my chances lol

here's my Spek's. Fuel pressure is in a TTS mount in the dash

What is it and what does it do lol link?:confused:

Basically a fluid filled diaphragm that transfers the pressure from the fuel to the fluid inside the isolator, which then routs into your cabin to the gauge. The fuel stops at the isolator mounted someplace in the engine bay, thereby keeping fuel out of the cab.

I just have one more thing to add, no disrespect ment here. Have you thought about fire in the cab?

Pure curiosity... Why are you interested so much in monitoring rail pressure? IMHO just log it when you want to check it.

Well I don't have a v2 handy all the time. I use my buds when I need it. It would be nice to see rail pressure under different conditions. And I'm pretty sure my lift pump is doin some crazy shit. That's why I wanted the fuel pressure gauge.

thanks for that explanation man. I'm not worried about a fire. Diesel is hard enough to ignite with an open flame. I'm not worried about it igniting from an electrical spark or whatever else could possibly fire it off. Plus, I'm counting on not having a leak haha

I agree with you Sean, it will be nice to monitor rail pressure under different conditions. And not all of us run around with a laptop or v2 all the time. I know I dont. Im all for more gauges, especailly the useful one like fuel pressure and rail pressure. Im just warning you like the rest of us, to not run fuel into the cab. It your truck, a 25000 one at that. No fuels coming near my face (thats a cover up for my leather seats:spit:)

i found out that with the isspro fuel pressure gauge i had to make my own wiring harness.....i said **** that noise and went ahead and cancelled the isspro and got a electric autometer. i like gauges because the second my truck does something strange or breaks down, i got plenty of gauges to help diagnose the problemo.

No one ever plans on a leak but it happens. And If you ever plan on drag racing or pulling your truck it will not pass tech. You can do whatever you want it is your truck but i would listen to what everyone is saying it is a bad idea. And i am not sure what you mean by diesel is hard to ignite with a open flame give it a try sometime and let us know how that works out for yea.

i did away with the mechanical because isspro requires you to nig rig your own wiring harness so i got an electric. and you can drop a lit match into your fuel tank and nothing will happen.....diesel needs to be atomized to ignite, just like gasoline.

I like the isspro deal so it's easier to daisy chain the illumination, power and ground wires.

me and electronic wiring dont mix at all....i tend to really mess things up that i try to wire. i can follow directions but the second i have to get off the wiring beatin path, shit gets dangerous

I would never run fuel into the cab and as stated the cheapo mechanical plus an isolator is usually more than an electrical, which is easier to install.

ISSPRO is so much cleaner of an install than the AutoMeter, it comes with all the wiring and simple instructions - you don't have to "make a wiring harness" in the way you may be thinking. The EV2s are great gauges, we've installed dozens of sets. The best part is that you can tell that ISSPRO makes them for diesels. Your boost gauges won't have cheap plastic T fittings for you to "put into your vacuum lines" like AutoMeter. The pyro probe is compression fitting not a leaky set screw in a sleeve. They make gauges that we need in all of their color options - boost, boost 2, pyro, pyro 2 (for compounds), rail PSI, fuel PSI, trans temp, engine temp, exhaust back pressure (drive pressure), etc. There is no need to mix match colors to get the gauges you want, and no using fuel or boost pressure to read drive, etc.

so the isspro back pressure gauge is a drive pressure gauge.....does the gauge come with all the stuff to run a DP gauge? copper line, etc...?

I don't know why anyone thinks that wiring a auto-meter electric guage is difficult because it isn't nor is it any more difficult then any other brand. I have one and installed it myself and it was a piece of cake.

As far as mechanical verses electric when it comes to fuel I do not recommend a mechanical one myself do to the possibility of a leak but if your bent on that one and you take every precaution in proper plumbing I wouldn't sweat it. Definitely use copper tubing ensuring that there is protection from rubbing and vibration not to create a wear spot and leak.

Problem is when installing if you get a leak at pressure it's going to get fuel in your rig so be prepared. In my opinion although it is fuel ,understandably it is at a much lower pressure than oil. Many individuals run mechanical oil pressure guages i the cabin and wouldn't think twice about doing so. Oil pressure in most cases run up to 60 PSI in regular gas rigs.

A friend on mine has a mechanical guage in his Chummins and has for many years without a problem. His truck needs a lift pump 2nd generation 24v and is well north of 15 PSI . But again I don't recommend mechanical.

My concern is a leak as if it ever did it will be smelly and messy! It will never leak at a opportune time and unless you have tools and gear with you on the road to stop the leak what do you do? I understand crap happens but diesel fuel in your cab? Totally avoidable. You could say the same about a mechanical oil guage but not many have them in our trucks so conversation about that is nill.

As far as high pressure mechanical guage goes in reference to rail pressure you are absolutely F'n nuts to run that into your cab! No way no how!
