Best Fuel Pressure Gauges of 2025

"This SENCTRL 0-100 PSI Fuel Pressure Gauge has proven to be excellent for testing fuel pressure, and I love its glycerin liquid-filled design that dampens vibrations for accurate readings."

"I found the gauge to be of good quality, with an impressive fit and finish. It works accurately and I haven't experienced any leaks."

"Using this gauge on my Holly Carb for my 350 Chevrolet engine was a breeze. It mounted easily and has been working well so far!"

"This is my second gauge purchase. The first one had all the liquid leak out from the back, so I'm hoping this isn't a quality issue—just bad luck. Other than that, it works great!"

"I've noticed a slight oil leak, and I'm really hoping it doesn't run empty in a week like the other three I've bought."

"I ordered this gauge a month ago, and after finally checking it before installation, I found a loose screw. It definitely feels like it lacks quality, and since so much time has passed, I can’t return it."

"I bought this gauge to mount on my fuel rail, and I was pleasantly surprised by how quick and easy the installation was. I had an accurate read on my fuel pressure in about 5 minutes. The gauge is easy to read and fits perfectly into the 1/8 NPT threaded hole, which is common for EFI applications. For the price and quality, it’s a great find!"

"Having used various liquid-filled pressure gauges before, I can confidently say this one stands out. It features a valve for equalizing pressure, which enhances its accuracy. I did notice a slight leak of gauge fluid when I pulled the plunger, but overall, it has been a solid performer for me."

"I purchased this gauge to keep an eye on my fuel pressure for my 347 stroker engine. The first one arrived without any oil, causing the needle to bounce around. However, the replacement worked perfectly. I was a bit surprised by the initial issue, but the gauge is performing well now."

"I’ve had this Fuel Pressure gauge in my car for about two months, and it’s been working great! The readings match my mechanical gauge perfectly, showing high accuracy."

"I installed this on my 2001 F250 SD in a custom center console. I didn't want to drill into the dash or use pillar gauges. I'm really pleased with how it looks and the color-changing feature. I even used sun bezels to angle it towards me!"

"After four months, my gauge started fluctuating above 50 psi. GlowShift was very helpful in replacing the faulty sending unit. They even exchanged my gauge for a new model that works perfectly now. Their customer service is top-notch!"

"I've been using this gauge for four months under my old Ford, and it's still holding up perfectly. No leaks, and it's easy to read even after all the mud and snow I’ve put it through."

"I replaced my old gauge with this one, and I’m impressed with how well it works. It fits my fuel pressure regulator perfectly, and I love that it hasn’t failed in over a year!"

"This gauge looks very professional and has been a great addition to my setup. The steady needle is a bonus, making it easy to get accurate readings."

"This is exactly what I needed. I had previously purchased two oil-filled gauges that wouldn't register once the engine compartment heated up. So far, this one is holding up well under heat."

"I bought this to connect to my Holley bypass fuel pressure regulator. The accuracy is impressive. Don't worry if it reads 1 psi out of the box uninstalled; it works perfectly when hooked up and under pressure."

"I wanted to share my experience, even though I returned the product thinking it was defective. It turned out to be an issue on my end! I received a free one from a friend after figuring out my problem, and it works like a charm."

"I bought this gauge to adjust the fuel pressure on my 12v Cummins. The size is perfect and it's easy to read. It seems to be a quality little gauge that should hold up well with vibration since it is fluid filled."

"I used this gauge to troubleshoot a fuel starvation issue in my 1973 Land Rover. I thought I had vapor lock, but after installing this inline before the carburetor, it showed 4psi fuel pressure consistently. My only issue was needing to purchase additional fittings, which made the setup a bit bulkier. Overall, it’s a great buy for under $10!"

"I received the product and installed it on a Holley regulator, but unfortunately, it didn't work, despite the regulator being new. I then tried a Holley gauge, and that one worked perfectly."

"I found this gauge to be an awesome buy! It has both high and low units on the aeromotive EFI to carb dual pressure regulator. I love the look, and it hasn't leaked at all. After dialing it in, I check it periodically, and I'm very satisfied with its performance."

"At first, I faced some frustration with my gauge. It read higher after idling for a while. However, after consulting my dad, I removed the liquid inside, and it worked perfectly. Now, it maintains 6 PSI ALL DAY!"

"I'm using this gauge for oil pressure on an old engine, and I'm really pleased with its quality and performance. The oil dampening feature works great, and it looks good as well!"

"I was looking for a visual gauge to assist in troubleshooting, and this one really complements my Sniper with the Holley logo."

"I wasn't trying to save money on this purchase. I went ahead and paid the price, and I'm happy to say that I got more quality than I anticipated."

"After installing this fuel pressure gauge on my Sniper EFI setup, it seems to provide accurate readings."

"I found this gauge to be solid and great looking for checking fuel pressure in my MG. It worked perfectly!"

"I had a vapor lock issue with my restored 55 Ford and this gauge helped me monitor the pressure effectively. It seems to work OK with my electric fuel pump."

"My husband has been using the Glycerin Filled Fuel Pressure Gauge and is overall satisfied with its performance and quality. The 1-1/2" black dial is easy to read and the 304 stainless steel case ensures its durability."
