Fuel pressure gauge

[MEby]

Ok, I did a search and found some discussion on FP gauges of various types. What couldnt find is, can I use an electric oil pressure gauge to monitor fuel pressure. whats different from a electric oil pressure gauge v. electric fuel pressure gauge.





I am looking at some right now and the only thing I see at this point is the fp gauge costs $120 more than the oil pressure gauge. is this the only difference?

This is a good question and I will also be interested in ideas. I recently installed a FASS system, so I'm wondering why I couldn't put a "T" in the fuel line with a oil pressure sender to an electrical oil pressure guage?

if I go with an mechanical gauge, where can I find isolators? and if I go electronic, can I mount the sending unit to the banjo bolt? thanks

only diff is you will have two gauges in your truck that both say "oil press" and an extra 120 bucks in your pocket...



at the drag strip it is against the rules to run a mech fp gauge in the cockpit w/o one of those high dollar accumlators. they do that for insurance reasons. AN stuff is not going to fall apart and spray diesel all over you (and if it did wouldnt you smell nice?). you probably wont be going 200 mph or worrying about rolling at 200 mph anyways... . so i think the best set up is a mech gauge with AN lines and fittings. a mech gauge is 10 times quicker when it comes to response - and sometimes they are more accurate as well...

Take a look in the Genos garage catalog, the Westach is pretty popular and I'm pretty sure that it dosen't even cost $120 It is electric, which I think is the easiest way.

With an electric gauage you have to have the sending unit also which drives up the cost.



Thelectric sending units are reliant that the source power is clean, reliable, and all your grounds are good. That gets to be problematic as the trucks get older.



Then you have the same problem you have with the OEM gauages "are they correct?" and they are notoriuos for being off. The inital adjustment and keep them adjusted is just a problem.



Get a mecahnical gauge, use and isolator with anti-freeze, and sleep soundly knowing when it says you have 7 psi there is an excellent chance it is correct for a long time.

If an electric gauge is used dont mount the sending unit to a banjo bolt. Get a small hose and mount it some were out of the way with that.

thanks guys, I am going to go with a mechanical gauge.

I prefer my Westach 30psi gauge over any other FPG I've used, numberous mechanical and Isspro electric. Keep in mind if your mechanical gauge is not well snubbed, the pulses from the mechanical lift pump will kill it in no time.
