Has anyone found a decent fuel pressure gauge? I’ve had a Moroso then a Holley now a liquid filled Aeromotive. Looked at the Aeromotive today and the needle is at 4 lbs and will not go lower. Used the pressure relief valve since it is liquid filled and did not change I’m not a fan of liquid filled gauges but thought it may be a better quality and can relieve the pressure for accuracy. Aeromotive said they would replace it but looking for options as I have not had good luck so far.

I have two AutoMeter mechanical gauges in the methanol system for my ECTA car. One is mounted in the gauge panel at the driver's position, and one is right next to the Aeromotive pressure regulator in the engine compartment to make things easy when doing a pressure adjustment. Both gauges are about 12 years old and I've noticed no problems at all. Both return to zero.

Are you talking the small versions that mount on a regulator or fuel rail? Never really had one to try. My std size Autometer has been faithful for decades. Though it was a filled gauge originally I drained it after finding out it changes readings with temperature changes.

Yes Larry, mounted just before Ford fuel log. Maybe just bad luck on my part....

same problem here , been through three , none work .

John if you are interested I have a New Autometer 2 5/8 ultralight gauge in box part#4411, that I will sell for $50.. Al

I believe I have a new Autometer 2 5/8" Sport Comp. Black face IIRC. I will have to find it if you are interested.

Al and Jared,
Thanks for the offers! Aeromotive is going to replace the one I have so I’ll give it one more try.

My 67 has a liquid filled gauge on the regulator.It has failed after 400 miles.It was a good quality one.Dale P has a box of leaky gauges and tells me to stay away from the liquid filled ones although I like them.They are very temperature sensitive and give you a different reading depending on the weather.I am going to just set the pressure with the new gauge and pull the gauge out..

Just spoke to Summit Racing and they are just sending a new one out, they don’t want the old one back which leads me to believe the new one isn’t going to last. Going to do what 427 Fastback did, set fuel pressure, pull it off and put a plug in the line
-
I'd re-think it. Pulling the gauge out after setting the pressure is not going to solve any problems. It is like doing away with an oil press. or water temp. gauge. You may not know you have a problem, till it's too late. One simple thing could cause a big problem. I like keeping an eye on my vitals, so I have all my gauges in the car. I used to have a mechanical fuel pressure gauge with an isolator mounted on the intake, but now I'm trying the electric to give a cleaner look and one less fluid filled line to worry about. JMO

I chased fuel pressure problems for some time with a liquid gauge and tried several different regulators. Actually read on the old FE Forum about the liquid gauge issue and bought the plain one. Pressure was steady but they all leak in short order. A few weeks back at the local speed shop while buying a new (and soon to leak) gauge the counter guy said " lucky you didn't grab a liquid fill one... they are shit". Yeah, I know that so why do you have so many different ones for sale here????
I'm all for buying a "quality" gauge as soon as someone can verify such a thing is actually made.

I do like to keep an eye on all the vitals.... thank god the oil and water temp gauges work without issue!!!! Not having an issue with fuel pressure but it frustrates me to have a gauge that I know is not reading correctly. Every time I’ve replaced one my initial reading has been where I want it and have not had one leak yet just never go back to zero. I’m with Posi67 and at this time I don’t see that a quality gauge is made at this time :(

I would recommend staying away from the liquid. We quit using them a long time ago. Only my opinion, but I would mount the gauge where you can see it while you are in the car. I know AutoMeter has a good reputation. They are made not far from me in Sycamore IL. I have used plenty of Autometer and had zero problems. I have three in my daily driver and have been in there for at least a couple years and they worked just fine this winter when the temp. was -34°F out. They functioned just fine. I am also a fan of the old Stewart Warner stuff. I see they are still making gauges, but not sure if they are they same quality they were:

Yup.. got a couple of the stuck needle ones as well. Figure they went bad before having a chance to leak. This was my last one and oddly, it only leaked internally.

Nightmist....we are talking about the little 1 1/4 round 1/8npt gauge that screws into your fuel line or regulator..Not your std 2 1/8 or 2 5/8 std gauge..It doesn't help that I have the gauge mounted to the engine...I have a street car..If the brand new pump fails the car will quit...If I have too much pressure the carb will flood..If I have to I will put the other Holley pump on.But a fuel gauge leaking gas on my engine is more of a risk than no gauge at all....JMO.

I understand that you were reffering to the gauge on the fuel log. That is why I recommened with my opinion to mount a different gauge in the car, or where it is visible from in the car. The only thing a log mounted gauge is good for is setting static pressure. It won't tell you if the pressure is creeping or going low due to some issue. It makes it easier to troubleshoot. I understand if the pump quits it will die. Been there. Knew it was fuel related because it sputtered before it killed. Ignition is smooth. Just checked the gauge to verify. Sorry for rambling on another thread.

Those - all of them - are absolute junk. Tap into that hole with a #4 fitting and run a line to a real 2 3/8" Autometer gauge. Nothing less. The TV weatherperson is more accurate than any of the low cost bitty fuel pressure gauges. If you are bucks up, you can use a Autometer sender to run an electric gauge in the cabin. That's what I use on the dragster.
