What Is A Good Fuel Pressure Gauge For Our Intakes?

Just what the title says. I'm looking for a good (But inexpensive) fuel pressure gauge that was designed to mount directly to the NPT fitting in the TPI fuel rail.

The Accel is def nice, but $70+ for a friggin gauge seems outta the park.

The next guy I was looking at was the Moroso, but I'm not it comes with all the necessary parts to be classified an All-In-One-With-No-Extra-Parts-Needed kit.

The Moroso looks promising, given that it doesn't require the purchase of a seperate adapter or extender to mount to the fuel rail.


Here is basically what I'm looking for:

- Something that would be permanately fitted to the car

- Something that is of good quality, and gives accurate readings (I know I read that the Moroso has a "Vibration Controlled" needle). I was told to stay away from the liquid filled ones.

- Something inexpensive but with good functionality and an all in one kit. No seperate pieces or adapters needed.




Well guys, any ideas?

Are you looking for the kind of gauge that mounts to the fuel rail, a separate gauge that needs a hose or one that you can mount inside the car?

The kind that mounts to the fuel rail.

Eventually later down the road when I redo my gauges the kind that mounts in the car, but that won't be for awhile.

You're probably not going to get anything good for cheap.

I used to use a small gauge that mounted directly to the fuel rail with a tall elbow adapter, but the needle began to bounce around like crazy after a short while. Summit then sent me a letter telling me that the manufacturer was recalling them because they were defective and could leak and cause a fire. I had removed the gauge earlier because the bouncing needle made the gauge essentially worthless. Summit did send me a check and a cap for my trouble.....this was years after I had bought the gauge. I don't even recall who manufactured the gauge. It might have been a VDO gauge

IIRC, I read someplace that these rail mounted gauges are for temporary use only...just for testing.

I now run an Auto Meter gauge. I disconnected and capped the gauge hose because I was cleaning the injectors thru the pressure port. Sorry for the dust and rusty fasteners. I wish someone would make a cup for the back of the gauge too. Since it's liquid filled, it's pretty impervious to foreign material getting into the gauge mechanism.

Bad place for a non-weather resistant switch.

Re: What Is A Good Fuel Pressure Gauge For Our Intakes?

I'm looking for a fuel pressure gauge setup as well, except just a put it on, tune and then take it off kinda thing.
The good thing about the Accel unit is the it's nice and short at the 90 deg bend. Since I have a 1990 TPI the stupid map sensor is right above the fuel rail where the fitting sticks out.

By the way I'm pretty sure that fitting that comes off the fuel rail is a -4AN male, not 1/8. Or wait.... don't tell me that GM put different ones on there depending on the year.... Sigh that would make GM sense.
