Anyone have A fuel pressure guage mounted on the cowl? looking to mount it outside were I can see it from the drivers seat, Electric guage are $200 for A 2 1/16 ouch Mech. guage are $60. please post pics of your guage mounted outside somewere.

Hit up Rob, Sy229. He has his FP mounted in the cowl.

I have a electric autometer phantom series fuel pressure gauge that I took out of my truck as I went to a different series gauge. It comes with everything needed. I can take pics if you are interested. $140usd shipped.

Dang, I wish that I knew that you had that before I did your parts...

My setup. We mounted it very low - only the top half of the gauge is visible from the drivers seat. Figured if you can't see the needle then it's time to pull over...

Do you still have a picture of this?

Was thinking of doing something similar.

Re: fuel pressure gauge mounted on the cowl

Is fuel pressure something you really need to monitor on an ongoing basis? A temporary test gauge with a hose long enough to reach under the wiper where you can read it through the glass, and a couple runs to convince you pressure is OK should be enough. Unless you change something, fuel pressure once checked and established as being "OK" should stay "OK".

Fuel pressure is just as important as oil pressure with boost. If a fuel regulator goes bad, filter cloggs, or pump goes weak and you get into boost it cant blow somthing up real fast. I have a fuel pressure gauge in every boosted or nitrous car ive owned. It also makes driveability diagnostics easy when you run into problems

fine.

You telling me you watch your fuel pressure gauge in "every boosted car you own", EVERY time you get into boost? Bull$hit. Gauges are useless if you aren't watching them at the exact moment other symptoms (severe detonation) occur. By the time you react (lift your foot) to the symptom (the detonation), the gauge reading (fuel pressure) is meaningless.

Indication of fuel pressure problems is usually associated with difficult starting, or detonation if nothing else has changed. While an operational symptom may be associated with one of the maladies you cited above, a quick check with a test gauge during diagnostics is sufficient to diagnose whether fuel pressure is associated with the driveability symptom.

My statement stands. I don't feel real-time fuel pressure monitoring is necessary for an established combination.

Gauges are useful for monitoring stable slow moving conditions, and comparing the indication to previous indications to assess whether the reading is above or below "normal", ie expected. A fuel pressure gauge meets this definition. Useful for monitoring for comparison to expected readings. My position is that fuel pressure isn't likely to change where it requires full-time monitoring.

Then whats the point of a boost gauge, most sytys use the ecm to control boost. Once its set up and confirmed then why use one? 99% of the time your boost stays the same especialy when its ecm controlled

i dont watch it all the time but if my wideband goes lean the fuel pressure gauge is a quick glance away

Re: fuel pressure gauge mounted on the cowl

I was going to ask the same thing.

Then again I like gauges, and we have oil pressure gauges and how often do we really have an oil pressure problems.

Who knows, you might be driving around and notice that pressure is a touch low and that the mustang at the stoplight just might not be worth it today. Could save you from a blown motor. Then again the fuel fitting could go bad, spray the engine bay with fuel, and torch your truck.

I say go electric or go home. I would rather not have (another) hose filled with fuel bouncing around my engine bay.

Re: fuel pressure gauge mounted on the cowl

I think electric gauges are needed when on the interior because of fuel in the line. An electric gauge wont have that issue. Kinda wondered about oil pressure gauges in the same respect.....

A mechanical gauge wont either,an isolator has a fluid like antifreeze between the isolator and the gauge.I agree with Dave,under boost I'm more concerned with were I'm going then what the gauges say.Only back in the 60's before shift lights did I watch the Tach,And this comes from someone whose sy looks like an autometer commercial.It has oil,boost,fuel pressure,egt,plx and trans temp.

Re: fuel pressure gauge mounted on the cowl

I use the pillar fuel pressure gauge to verify that my FP is rising with boost at wot. It was to flatten out or drop, it could be a fuel pump issue. I don't want to lose a motor over $100 walbro fuel pump going out. I have never had a fp go out but I know of others. Hopefully I would notice the timing getting pulled out on the scan tool or wbo2 going lean first.
