As title says, would it be too safe to run a Fuel pressure gauge in the cabin? Im going to be swaping my v-6 (with a broken bottom end ) To a carbed v-8, running no more than 7psi of course. I do plan on upgrading to a nitrous system, so i figures a three guage A pillar would be good, with A/F ratio, Fuel pressure, and a clock or a nitrous pressure guage ^_^

I have seen the price diff between the electric pressure guages and the mechanical, and i dont know how unsafe it would be with a fuel line at only 6 psi if i properly routed it away from wires, and if it did leak, to drain away from the cabin area, and any electircal.

 

Running any type of fuel line inside the car is extremely dangerous please do not do it.
They make a fuel isolator that goes outside the car it is a diaphragm with fuel on one side and a non flammable liquid (not sure what it is) on the other that goes into the car
If you have ever seen a pic of my car my fuel gauge is mounted outside my windshield because I bought the guage in the mid 80's right before they came out with the isolator

I have my gauge mounted in the engine bay...I say heck with mounting a Mechanical Fuel PSI Gauge in the cab....toooooo risky

Well, I was just looking at my Jeg's catalog and the price difference between the mechanical and electrical gauges was like $90. Quite a chunk of change. However, hooking up the electrical gauge will be easier and probably be more accurate. Plus, what happens if for some reason the isolator goes bad on the mechanical gauge? You'd be spending more money. Not that I've seen that happen, but it is possible. Personally, I think electric gauges are the way to go unless the gauge you want isn't offered in an electric unit.

 

So you know your F/P while your car isn't moving.

 

So your saying every fuel PSI gauge made is supposed to be mounted inside? It's cool that electrical fuel PSI gauges are available so they can be mounted inside...but with a mechanical gauge mouted inside? That's really not a good thing to do. It's ment for tuning reasons... If you do a search...there are tons of members who have there fuel PSI gauge mounted in the engine compartment....

 

No, they just have little value. For real world tuning you need to know what going on while the engine is under load. Under hood F/P guages are little more than eyecandy. True, lots of people have them, and they do have a limited purpose. I would just rather have one that I could monitor under different circumstances, not just in the garage. I never said anything about mounting a mechanical F/P gauge inside the car, though you can use an isolator or you can mount it just outside the windshield on the hood or you could get an electric one.

 

If i had a cowl, i would mount mine there so that i could view it from inside. guess ill have to save up for this expence

 

Just to give you an idea so its not mounted to the hood

 

Wow that car looks intimidating.

 

not to mention these guages are sensitive to heat, prolonged exposure will drastically affect their accuracy.
