MEASUREMAN Fuel Pressure Gauge Kit 0-15Psi Stainless Steel Glycerin Filled, 1-1/2" Dial Size, with 5/16" Fuel Line Fuel Pressure Brass T-Fitting Adapter, Lower Mount

Works perfectly with my Facet 4-7 psi electric fuel pump and reads good. No higher than 6 psi (Edelbrock carb likes no higher than 6.5 psi) and no lower than 4 psi. Super simple to install and no leaks. I didn't install at 90 degrees as the gauge wouldn't be readable, so I did 45 degrees and liquid below vent hole. My only gripe is it could've used a little more glycerin. UPDATE: I decided to contact the seller and replace only the gauge since the glycerin was so low, way lower than they state. Email gives you a "can't deliver" message, site is non-functional and no phone. I just ordered another gauge from a different seller.

Meets expectations. Installed it as per the tiny instructions on the gauge. Mounted it on the throttle body fuel outlet using a adapter fitting on a 65 psi fuel system. Fired up the engine. Gauge worked perfectly. No drips, no runs, no errors.

looks good for the carbs

Needed this on an old ford truck with a 390 and an edelbrock 1406 carb. They can’t run over 5.5 psi so I wanted to know for sure how much pressure I had from the factory mechanical fuel pump. Turns out I’m around 3.5 so no pressure regulator needed. This worked well and I have left it permanently installed. Down side is the fluid filled gauge. It’s has a bubble in it and I would have preferred it filled full or none at all. Seems weird to see water in the readout and a visible air gap. It’s also fairly heavy so it needs to be mounted or zip tied to something sturdy. I have a PCV hose that runs along the fuel line and it’s secured to that for additional support. Overall it’s worked well. Priced fairly. Seems sturdy.

Gauge works excellent built tough just put it in and we’ll see how it goes from there

Good product, Excellent accuracy.

Worked perfectly and gave the exact readings I expected. Used with an M12 Banjo to 1/8 NPT adapter to test fuel pressure on my 21 year Lexus RX with 300,000 miles. Same fitting will work for Toyotas. I don’t know if this is rated for permanent installation but I will only be using it for testing. Please do not permanently install a gauge in your fuel system unless it is rated as such. Even then, install a valve so you can turn it off when not in use.

Total garbage! May burn your car to the ground! Day 1: The first thing that I noticed was that the needle bounced around more than Tigger on a meth binge. It was also reading 15psi higher than the actual fuel pressure. Day 2: Gauge fogged up and droplets on inside of glass. (See Photos) Day 3: MAJOR Fuel Leak during a drive, dumping gasoline directly onto the exhaust headers. When I was about 10 miles from home, I noticed that the EFI display indicated that the water temperature dropped 10-15 degrees, but the mechanical gauge remained the same. Odd, but nothing to worry about. .....or so I thought. 15 minutes later, I pulled into my shop, got out of the Jeep, and noticed a large puddle on the floor and the smell of gasoline. I popped the hood and saw a steady stream of fuel leaking out of the pressure gauge, directly onto the header tubes, and running down the side of the block. (The temperature sender on this Jeep 258 (4.2L) engine is located in the side of the block, directly below where the gauge was mounted to the EFI. When the gasoline ran down the side of the block, it flowed over the temp sender which caused the perceived sudden drop in water temperature during my drive) The leak from this defective gauge could have easily caused started a fire and burned my CJ-7 to the ground. I got lucky. You may not...
