Any recommendations?
Not looking to spend over $100. Must go up to 100 psi. I really don't care what it looks like. Must be in car.

Let me know.

Thanks.

electric fuel pressure for under 100? id buy one if anyone could find one

doing some quick searching the only fuel pressure gauge i could find for 100$ or less new was on ebay, it was a no name brand so i dont know if i would trust it or not. i'd search for a brand name, known working, used one.

Damn I didn't realize they were so expensive. I went on eBay and there are so many choices and it seems like the autometer ones are pretty high.
Looking for a used one is a great idea.

Yeah fuel pressure gauges for EFI aren't cheap, especially when you want it to be in the car.

If you choose the 80 psi unit, you may be able to get a cheaper mechanical gauge, and be under/around $100. But IDK what kind of failsafe is built into the isolator. I personally would spend the other $100 +/- for an electrical unit. Burning is far more expensive.

If it means saving for 6 months, it would be worth it to me.

^^^Thats very nice!

Wasn't really paying attention, but what do you mean by "Burning is far more expensive" ? How do those isolators work?
I take it its a safety feature for the gauge because of all the pressure? Feul + spark = burnnnnnnnn!

You would think something like this would have a safety feature?

I just got to thinking.. I have the AE ScanGauge and I have one more analog input left... I could just get a sender and hook that up to the scan gauge...

Found it...

Looked like I would need the -4an fitting for the schrader valve. Damn $25 for that add on.

So if your fuel rail has the port on the end, you have $90 plus shipping for a cleaner set up.
Yeah I meant burning, as in having 60 psi fuel spraying inside your car. I'm sure those isolators are pretty reliable, as they are listed for in cabin use. But being a diaphram basically, it is a mehanical part that may eventually fail.

I would go the scan gauge route, as fuel pressure is fairly reliable and steady. You only really need to check it occasionally, or when trouble shooting. It's not like if the pump suddenly fails in a high boost situation, you're going to react fast enough to make a difference. But for that occasional hiccup, it is nice to be able to confirm, or eliminate one possible cause.

Thanks for all the advice man. I ordered that sensor kit.

Yeah I have a schrader valve at the end of my S3 fuel

Which brand should I go with?

I need a 4AN fitting with 1/8'' NPT port.

Aeroforce tech wants $25 for theirs. I see summit has different brands but not sure which one to go with..
Any other suggestions?

I would just go with the edelbrock one. it seems to be the cheapest and they are a fairly well known and highly reguared company

Hmm found this thread on srtforums and replied... Still not sure what to go with.
