Good day gents! I want to use a mechanical fuel pressure guage, and have some questions. I noticed some are plumbed into the cab right to the guage, while others "strongly recommend" using an isolator between the guage and the fuel source. I also noticed that the isolators cost a considerable amount of money more than the guafe does. Should I use an isolator? What is the advantage? Is leaking fuel into the cab the major/only concern? Should I abandon the mechanical guagfe and go electric? Any and all opinions welcome.

PS: I am trying to decide between DiProcol black face and Isspro right now. Any preferences?

Isolators tend to die for no reason.
For something that costs more than the guage itself, not good.

Not sure on the DiProcol, but Isspro's can handle Diesel directly to the guage.
Many have done it this way for many many miles with no problems, which is why I chose to.
I was worried about fuel in the cab initially, but after talking to a couple people, figured it was ok.
Diesel in the cab isn't that big of deal, it doesn't explode like gasoline likes to, and I prefer the smell of Diesel fuel over antifreeze.
Needle valve in the line to dampen the injector pulses, and shut off the fuel should a leak occur.

Mechanical guages seem more "real" and accurate to me then electric, and less things to go bad and give false readings.

My 2 cent opinion.

I'd go with mechanical gauge no isolator.I like the Isspro gauges.
Take your time do all connections right you should have no problems.

Isolators tend to fail, what good is gauge that you can't trust?

It's the law in some states that FP gauges be sold with isolators, that's the reason you see them sold together often. The law only applies to sellers, not users.

Yea what PHOX said above.
Give Rod a call, he has the complete setup.

Thank you for the input. I am definitely leaning toward the Isspro's. Any one from the DiProcol camp have a reason I should lean that way? I am considering these brands because I have heard that they are both suitable for direct hook up for diesel fuel.

I want the EV line pre-turbo colored Isspro pyrometer, Isspro or DiProcol for the remaining Trans. temp, fuel pressure, and boost guage. I like the double Westach principle, but am not fond of how they look. I don't like the looks of the x-monitor either, with its rectangular face. I saw an add one time for a 4-guage a-pillar pod, but I can only find them listed for Fords now.

Phox -- where did you hook on for the fuel guage? What is the needle valve for dampening fuel pulses? I am very interested in your setup. Thanks again everyone!

I had Autometer electric and couldn't keep a sending unit working...went to the ISSPRO mechanical tubed with 1/16"stainless tubing with a needle valve for shutoff (incase of leaks)...love it and have not had any problems or smells...do a fuel press guage search and you will have many hours of reading to form your own opinion...

I have all Di Pricol gauges and am extremely happy with them... fp is plumbed with no isolater and I have no problem with diesel fumes or fuel in the cab.

I need to get a pic of my setup.

I know Shovelhead has a pic of the needle valve in his album.



It's the gizmo connected right to the filter cap.
It's what you'd use on a swamp cooler water hookup.
This is what the 99 filter cap looks like, they changed it 2000 on.
You completely close the valve, then open it slightly till you get a constant reading.
If you should happen to spring a leak, closing the valve will stop fuel flowing to the guage and it's plumbing.

I have mine hooked up on the bottom of the filter cannister, which is where the fuel fittings moved with the new filter cannister design.
Only problem with mine is my large arms and hands can't quite fit down under there to close the valve if I need to.
I had to borrow my 10 year old daughter to adjust the valve the other day.

Very slick! Thanks, Phox! Looks like both a very user friendly and safety oriented install option. Any special brand you recommend for the stainless hose, or does the kit usually come with one?

amartinson

As you can see, I have the same problem.

Just got my Isspro set up from Rod @ www.wildcatdiesel.com and am loving it.

phox_mulder

Yes, Rod at Wildcat got me my setup as well.
Included everything, stainless line, needle valve, banjo bolt, washers, everything.

Without being too nosey.......how much was hose, valve, etc from Rod I already have a new ISSPRO.

phox_mulder

I'm at work, paperwork is at home, I think it was included in the price of the guage kit.

Wouldn't be nice to quote a price anyway,
as they might have changed, the price of stainless steel fluctuating due to that conflict overseas and all.

Thanks for the number. I didn't find the price on the website.
