Which way is cheaper? Going to a shop or buying the parts and doing it myself? What tools do I need and how much? I fixed the loose wire on my fuel pump and it still stalls. It used to choke, die for a few hours then worked like nothing's wrong. Now it stalls but doesn't die. Could it be anything else? Thanks.

How to make a fuel pressure gauge

This is what I did,

I went to Autozone and bought the following:

1- a 5/16 brass barbed tee fitting. 3 barbs, each 5/16.

2- 1 brass connector with 5/16 barb on one end and 1/4 NPT male fitting on the other end.

3- a brass 90d fitting with 1/4 NPT female on each end.

4- 1 foot of kevlar lined high pressure fuel injection hose.

5- 4 Fuel Injection hose clamps

Went to Home Depot and bought :

1-a Pressure Gauge 100psi from the plumbing section. (used to check water pressure levels) It has a 1/4 NPT male end.

2- teflon tape

Total cost: $14

Depressurized the fuel line, cut the hose just after the fuel filter, put the T inline, clamped on tight, put the 1' hose on the T, the other barb into the 90d, the gauge into the 90d and mounted it by clamping the 90d onto the fenderwell just above the fuel filter.

My pressure reads 33 psi and I'm glad to know that that is within spec. I'll post a photo of it tomorrow.

Re: How to make a fuel pressure gauge

> Steve,

Is there another place ( OSH? ) that I can go to besides autozone. I don't think there are any around here in San Jose Ca.

What does 90d and NPT stand for? I want to put one on my car.

The gauge was $6.95, the fittings were $5.95 and the rest of the stuff I already had. But I think if you start from scratch you are tops $20.

Photo of my fuel pressure gauge

The barb fittings should be available at any competent autoparts store. The pressure gauge should be available from a plumbing supply house or major home improvement center. Sears even.

Here is a photo of the finished product

Cool Photo - but different

Steve,
I installed a slightly smaller gauge and actually installed it in line with the fuel line rather than 'T'ing off to a fiender well mount. Wish I had a digital camera so I could show you. Actually a bit simpler installation.

Phantom; Cool Photo idea

Hi Phantom. I know of an easier/cheaper way to get pics on your pc besides scanners or digital cameras. Get a cheap disposable camera. 25 exposures preferably(usually with 27, I don't know why). Take your pics. Turn it in for development as usual, but ask for diskette form. You can then download the diskette onto your pc. It costs about the same price as normal development + the diskette which is about $4. I usually get them developed both ways. This is how I got my pics for my web site. I also have pics of the things I do at work. Mainly for a future webpage for advertisements of my upcoming business. Hope this helps you if you didn't already know of it.

Yeah, I would have done that if I had found a smaller gauge at the local hardware store. I was in one of those do it right now frames of mind!

But I do like the fender mount actually. Looks very technical.

Where did you say you got your gauge? and how much?

Hi Steve, I just installed a gage, ala Phantom style, 0-100 psi-glycerine filled from a performance shop...cost $35, 1 tee and 2 hose barbs $5.32. Looks good..just sits right on top of the filter.

Got it at Harry's Hot Rod Shop in Grand Prairie, TX.
and how much? $40.

The gauge had the inlet in the back instead of into the bottom so I installed it in the straight through part of the T straight up from the fuel filter. The right angle part of the T then was connected to the hose that goes to the fuel rail. That way you look straight down at the face of the gauge. It's only about 1 1/4 in daimeter so occupies very little space.
