fuel pressure gauge

[xjon]

Which gauge should I get? I'm getting the autometer but they have 2 guages, 0-100 psi or 0-15 psi with isolator? Which one do I need?

BTW the part numbers are 4363 (0-100), 4313 (0-15)

You want the one that reads 0-100 psi. Your static fuel pressure is about 43 psi to give you an idea (0-15psi is for carb motors I believe). The reason for the isolator is if you want to put the gauge in the ****pit of the car. You do not want to have pressurized fuel lines inside your car.

yes, that is correct.

Alright, I'm sold! I'm going to buy the autometer dual gauge pod for my s13. One of the guages will be my boost gauge and the other...should it be the a/f ratio or the fuel pressure gauge?

thanks.

i would look at both.....i chose the AF & boost.....but now am tossing in the FP gauge.

I read in a book that it is more important to have a fuel pressure gauge than the AF ratio.

The problem with running an A/F gauge is that it is not very accurate. To really have a useable A/F gauge you need to have wideband sensor. Most cheap A/F gauges do not use a wideband sensor because they are so expensive. A narrowband A/F gauge in my opinion is a waste of money. I would rather have boost and oil pressure. I've got a coolant gauge but haven't installed it yet.

I've also got the fuel pressure gauge that I will sell if you are interested. I decided not to use it. it is the 0-100psi, looks the same as the picture.

Email me if you are interested. I'll sell it for cheap. New in Box.

Thanks jay, but looking for the pro-comp silver face.

I have a Ultra Lite autometer boost gauge (2 1/16" silver bezel and face) if you want one. What size are those Jay?

I second not buying a a/f gauge... lots of other good things to spend $40-50 on, like oil pressure or oil temp.

My setup will have a oil pressure, boost and water temp (maybe).

What are people's feeling on using the stock water temp gauge? I was thinking of maybe using the stock one and getting a oil temp instead. As long as it lets me know if I am overheating the stock one should be fine.

got the boost gauge already and the a/f gauge. Now I want the fuel pressure gauge.

I really don't want to fill up my car with guages. Just the necessity.

In that case, remove that a/f gauge, it'll only mislead you and make you think all is well when in fact you're leaning out terribly. They are worthless.

Unless you want a good light show... I agree with selling it and use the money for something useful. You'll probably get most of your money out of it on ebay.

where do you think I got it from!
