Hey guys, just wondering where you guys got your fuel pressure gauges that mount on the fuel rail. I've seen the steeda website and its 50 bucks, seen one on ebay for 26, but I still think thats high, these look like they should be 10 bucks, just wondering where you guys got yours and whats the cheapest place to get it? Thanks.
 
I wouldnt cheap out on a fuel gauge. Not only will you have a strong chance of it being inaccurate but it may also be more prone to leaking and thus causing a fire and destroying your car. :notnice:
 
Fuel pressure gauge adapter fittings:
Holley Performance Products Flare to Pipe Fitting 17945NOS AN 4 to 1/16” pipe
Holley Performance Products Female-Male Adapter 16785NOS 1/16” male pipe to 1/8” female pipe

Or
See Auto Meter

I made my own pressure gauge and holder. I bought the NOS or Autometer adapter that you screw into the place on the fuel line where the schrader valve goes. You have to remove the Schrader valve, but save it, since you will reuse it. I ran a piece of SS (stainless steel) braided hose to a 1/8” pipe brass tee fitting that I mounted on the fender well by the MAF. I made a mount bracket out of aluminum angle I got from Home depot and bolted it to the fender well. Then I mounted the brass tee to it with some machine screws and a plate. I sandwiched the brass tee between the aluminum angle and a flat piece of aluminum that I trimmed off the extra aluminum angle. Three screws laid out in a triangle pattern go through both pieces of aluminum to clamp the tee in place. Put the Schrader valve in the spare port of the brass tee. I used a cheap industrial gauge from MSC Direct (Industrial Supply Equipment from MSC Industrial Supply P/N 56468499). It works great and was cheaper than (less than $6) anything Summit had.

If you look through the MSC Direct catalog, you can find any type of gauge you want, including liquid filled. You only need a liquid filled gauge if you mount it directly on the engine. The liquid filling dampens out the vibrations. Decide how much you want to spend and what size gauge you want and they have it

You can buy the Autometer Stainless Steel braided hose for like $60. Or a local shop that makes hydraulic hose assemblies can make it for you at a cheaper price. Ordinary low pressure hydraulic hose can be used in place of the Stainless Steel braided hose, the Stainless Steel braided hose just looks nice. I got mine for $4 at a place that sells industrial and military surplus parts of all kinds. The Stainless Steel braided hose goes for about $3.60 a foot and the fittings are probably about $5-$8 each. You can make your own and save some $$$, the shops may have a setup or labor charge to fabricate the hose assembly.

Locally in Orlando, check out Skycraft on Fairbanks and I-4. They often have the hose and fittings you need for a very reasonable price.

Ok heres a story.....i built my motor and went cheap on the fuel system at first....got a $25 Regulator off ebay....hahaaa crapola ...Well i would rev the engine and it would drop pressure. That didn't stop me yet!!! Nope not until i had it fail on me!!! Came off the higway after my 1hour commute home from work. The car was put putting and wouldnt go faster than 10mph....pulled to the side of the road, popped the hood....gauge read 5 psi no matter how much i turned the lil screw. To get it home i had to clamp the return line with vise grips to get enough fuel pressure to get home. Well after that i went overkill on the fuel system....my regulator is $150 Aeromotive. But i atleast recommend a Kirban or Aeromotive makes a regulator that goes on the rail with a gauge i believe. Personally a regulator without a gauge is worthless to me. When you go cheap on a regulator it will eventually let you know. When it lets go you'll run piston melting lean.

Aeromotive :nice:

93vert383 I was talking about those little gauges, not the fpr.

Joe I had seen your post when I searched but I didnt want to mount it on the fender I just want a simple one that goes on the schrader valve.

Thanks for the info guys.

Oops...Sorry it was early and i was getting all thread happy on my 2 cups of coffee. I'm used to using the Gauge thats attaches to the regulator body.
 
What don't people understand YOU GET!!!! WHAT YOU PAY FOR!!!you go cheap you get junk.You buy junk you get junk.In the end your car is yup, you guessed it, JUNK!

That's what is nice about my setup you can spend as little or as much as your wallet will allow.

The 2" 0-60 PSI, 1% accuracy, liquid filled gauges are running $65-$81, so a less expensive gauge may be better suited for the wallet for most of us. The 1% accuracy means that the maximum error is +/- .6 PSI

The 3% accuracy gauges are running $3-$8. The 3% accuracy means that the maximum error is +/- 1.8 PSI.

Most of the gauges you see at Summit and other auto specialty stores are probably 3%-5% accuracy.

It takes a significant change in pressure to make much of a flow change. Example: a 19 lb injector will flow 24 lbs at 63 PSI, and a 24 lb injector will flow 30 lbs at 63 PSI. That's a lot of pressure increase to get a flow increase.

See Automotive Performance Software / Interactive JavaScripts Calculators to get the calculators used in these examples.

Because of the significant pressure increase need to increase injector flow, a 3% accuracy gauge would probably work fine and you would never know the difference.
 
If I use an adapter though wont I need something to actually push the schrader valve to get the pressure? Maybe im confused on how it works.

You remove the Schrader valve and install the adapter. The adapters come in two flavors: one with a - 4 AN flare for use with a hose, and one with a 1/8" female pipe thread.

That's the problem with most kits is that you have no Schrader valve to dump fuel or add another gauge to check the accuracy of the one already installed.

That's what I like about my setup - you get the gauge of your choice (or maybe your wallet's choice) and the Schrader valve to dump fuel or check the gauge accuracy.
 
the way i was referring to use it as j rick. said you just remove the schraeder valve and screw the adapter in place... since i did that ive installed a nitrous setup on my car so i had to use that port for fuel, so now i have a gauge that screws into the side of my regualtor...

The Kirban KP-1441 fuel pressure gauge that I have comes with an adapter that screws directly onto the Schrader valve. You will not need to remove the Schrader valve at all. Mine works great and gives a nice steady reading. It costs a mere $50 from 86-01 GAUGE, MECHANICAL FUEL PRESSURE MUSTANG
