Nag, nag, nag, ... get a fuel pressure gauge

[klenger]

So I started looking at Geno's to see what I should get. Surprise, only two of the lines they carry offer a fuel pressure gauge, the Di-Pricol and Westach. I really don't care for the look of the dual boost/pyro of the Westach, so that leaves only the Di-Pricol if I want the same brand for the whole set. Problem is, I kind of prefer the electriconic interface of the Westach FP guage. The nice people at Geno's said that Autometerhas a FP guage, but that it's too expensive, so they don't carry it.



What should I do.



My truck has 23,000 miles on it, and the fuel pressure has never been checked as far as I know. Funds are limited right now, so I'm thinking about getting a FP gauge to hook up temporarily for test, and then install the whole set when I win the lottery.



Note: I posted this earilier on the "Which Gauges" thread, but it seems to have died, or I killed it, so I thought I'd try again.

Buy an Autometer 0-35 PSI boost gauge and run it as a FP gauge. I did this, as have many other people. I have about 5k miles on mine now and, knock on wood, no problems. You're not going to break the plastic boost line with 15 psi of fuel in there, as I run 35 psi of air through the one to my boost gauge every day.



Mine is connected post filter, and also has a needle valve right there as well so that should I ever enounter a leak, I can shut it off at the source. Works well, and I never have to worry about a sender going out. Now just to find another place for another gauge (I have pyro, boost, and transmission temp on the pillar).

Call Piers.

I had one on order, till some money crunching came about, but they have an ISSPRO made for the 12's, and I think it measures to 40 PSI... . With Isolator kit as well. . Call and talk to them, and do it the right way.

Also they need to be as level as possible with the gauge. I ran braided stainless, but some people run the plastic tube and cover it with vacuum or some type of rubber hose.

Summit seems to be cheaper than anyone else, but I do like the way Geno's garage pillar fits, you can use it to replace old pillar with a little modification, they also have cheap transmission temp gauges and steering pod gauge mounts

Josh,

Does that setup push fuel into the cab or is it isolated within the engine compartment? I thought boost was an air pressure guage and not for fluid? Please help an inquiring mind get straightened out... ...

I bought the Nordskog Digital

from Summit. $86 buck for the gauge, sender and mounting cup. Reads to 16 psig and has high / low memory. Here are some pics.

First who's Josh? or did you mean Gosh?



Boost is an air pressure gauge. I have heard of people using them for fuel pressure. Do a search you'll turn up plenty. If you've browsed for fuel gauges you will find they come in two basic versions, 0-100psi and 0-15 psi, and that is one reason people by the 0-30 boost gauges and use them for fuel press.



Yes I have fuel in the cab, no leaks. I originally bought the isolator, but it was such a PITA, plus accuracy would suffer since I wanted to put it in the pillar. I decided to go with an experts opinion and just run braided stainless. A prefabed hose cost the same as the isolator, and is much easier to install. With a mechanical gauge you don't need to worry about losing sending units. I decored the schrader on the vp44, moved it to the bottom of the fuel filter canister and hooked up my braided stainless to that.



Hope this answers some of your questions.

 

[snowracer69]

Yep, I have fuel right behind that gauge. No isolator at all. I learned about doing it this way from illflem who has done a few trucks like this, including his which I believe has been trouble free for 2 years?! I too was on a strict budget for this gauge, and wanted all 4 of my gauges to match... so, I went this route. Total cost was about $70... that included the gauge, all fittings, the needle valve, and the 6ft of vaccum hose that I protected the hose with. Also, the needle valve is only open about 1/8 of a turn... just enough to get an accurate reading... that way if something does happen the leak will for one be pretty miniscule, and for two, I can shut it off almost instantly.



The way I look at it, pressure is pressure to a gauge... it doesn't care what's pushing on it (because I don't believe the fuel reaches any internals of the gauge, but maybe I'm wrong... time will tell I guess).



Anything else I can help you with, just holler.

Remember.. Save a little money, and you get what you pay for...

It will come back and bite you in the but twice as hard down the road! I do not take shortcuts. Go the extra mile now, and you will be rewarded down the road!

[snowracer69]

charlan...



Have you actually used the mechanical boost gauge as a FP gauge and had it fail on you?



You say it will come back to bite you twice as hard... . please elaborate on this, as you seem to think it will destroy my vehicle to have a mehcanical boost gauge being used as a FP gauge, with fuel being ran into the cab.



Just questioning why you think it's so wrong. You didn't provide any details in your initial post.



Josh



BTW, many people have done this with much success. Surprised illflem hasn't jumped in here yet.

 

[C. Harlan]

Don't get me wrong, to each his own. . With that said, Diesel fumes make me horny and all, but I just do not like the idea that if that gauge which is made for AIR PRESSURE begins leaking fuel, and gets into your interior, you are really up dookie creek without a paddle. why not just go the RIGHT WAY, get an isolator kit, a FUEL PRESSURE gauge, spend the extra dollar, don't be cheap for once, and not have to worry anymore... Just my opinion. Chime back if you like. Have a great day today, and a better one tomorrow!

Oil pressure gauges for years have been with oil up the gauge in the cab! Seems like if there was problems with that they would have stopped making or selling them. Seems to me that diesel up to the gauge would not be a problem.

 

[Joe G.]

My old mechanical gauge must not have known about that. After many miles, one morning I noticed a moat around my transfer case shifter. Not too deep, but it smelled up the joint.

 

[illflem]

Five years with diesel plumbed into my cab without a drip. I've installed similar setups on half a dozen other trucks with no complaints. Seems I hear more complaints about isolators leaking.

Chris, very few gauges are made for just one specific material, one size fits all. You'd probably have to pay up the ying-yang for one rated for a single material.

How about this one... . $38 from www.isspro.com



0-35# Mechanical Fuel Pressure Guage

Also available with red pointer and/or white face.

Part Number

Do you know the part # for the 0-35 guage fron Isspro?? I can't seem to find in on their web site. Thanks... ...

 

[CUMAPART]

rjrepo,

I run the 0-35 Isspro got it from Piers at PDR. I was gonna run straight fuel into the cab but he told me about this new isolator he had so I went that route. I had to make my own rubber line coming off the schrader at the injection pump to the isolator but he says he has the rubber line with the fittings in stock now. Works great

 

[Dkevdog]

For those of you who want another option for an electric setup, If you are willing to wait a little longer, Isspro is going to be offering the 0-30psi EV series gauge as electric very soon. It will be available with white or orange pointer, and look virtually the same as what has been pictured above. The original expected release was Mid-March, but I haven't heard anything about it hitting the shelf soon... ... ...

Here is the part number for the Isspro Fuel Gauge:



Isspro Part #

Black: R5604

White: R6704



If anybody cares. These look sweet with the red pointers. I can't find a picture with the red pointers.

 

[DMC]

Could it be R5604R would be the part number fo the 30 psi fuel pressure gauge? If so, who carries them? I am really ready to get gauges and want a matched set of Isspro EVA Series.





Thanks
