Available in 0-100 or 0-15 PSI pressure ranges, our gauges cater to diverse monitoring needs, from daily driving to competitive racing. What sets our gauges apart is the innovative liquid-filled design for enhanced durability and an integral equalizer valve that accurately maintains pressure readings.

Review: Clean - great product always love aeromotive quality, easy install and it's easy to read, accurate, + the design is sleek , fits good too Review: High Quality Gauge - Easy install, and works great. I had a cheaper gauge on an Aeromotive regulator as part of the regulated return fuel system I installed on my 6.0 PSD in my '06 F250. One day I noticed a fuel leak coming from the truck and upon opening the hood found the gauge cracked and leaking fuel. I don't expect that from this gauge as its much higher quality. Interesting that the kit manufacturer used a premium regulator and a bargain basement gauge. ## Features - ACCURATE FUEL PRESSURE GAUGE READINGS: This liquid filled fuel pressure gauge measures fuel pressure from 0-100 PSI, providing reliable monitoring for EFI and carbureted automotive engine applications - LIQUID FILLED WITH EQUALIZER VALVE: Built with an integral equalizer valve that equalizes the gauge case to atmospheric pressure, helping maintain accurate readings despite temperature changes - DURABLE FOR UNDER-HOOD USE: Liquid filled construction improves durability and vibration resistance, making this inline fuel pressure gauge well suited for harsh under-hood car engine environments - 1.5 INCH EASY-READ DIAL DESIGN: Features a compact 1.5 inch diameter analog dial with clear markings, allowing quick visual fuel pressure checks during setup, tuning, or diagnostics - 1/8" NPT MALE FITTING COMPATIBILITY: Designed with a 1/8 NPT male fitting, this fuel pressure regulator gauge installs directly into compatible ports on fuel pressure regulators or fuel system fittings ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001O06BGM | | Best Sellers Rank | #44,298 in Automotive ( See Top 100 in Automotive ) #8 in Automotive Fuel Pressure Gauges | | Brand Name | Aeromotive | | Customer Reviews | 4.6 4.6 out of 5 stars (569) | | Global Trade Identification Number | 00684980002560 | | Included Components | Aeromotive 15633 Fuel Pressure Gauge - 0 to 100 psi | | Item Type Name | Aeromotive 15633 Fuel Pressure Gauge - 0 to 100 psi | | Item Weight | 0.18 Pounds | | Manufacturer | Aeromotive | | Material Type | Stainless Steel | | UPC | 684980002560 | | Unit Count | 1.0 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Aeromotive - **Global Trade Identification Number:** 00684980002560 - **Item Weight:** 0.18 Pounds - **Material:** Stainless Steel - **UPC:** 684980002560 ## Images ![Fuel Pressure Gauge 0-100 PSI - Liquid Filled Inline Fuel Pressure Gauge, 1/8" NPT Male Fitting, 1.5 Inch Dial for Automotive Engines - 15633 - Image 1](https://m.media-amazon.com/images/I/71MXg2GHhLL.jpg) ![Fuel Pressure Gauge 0-100 PSI - Liquid Filled Inline Fuel Pressure Gauge, 1/8" NPT Male Fitting, 1.5 Inch Dial for Automotive Engines - 15633 - Image 2](https://m.media-amazon.com/images/I/81hRyy5YGwL.jpg) ![Fuel Pressure Gauge 0-100 PSI - Liquid Filled Inline Fuel Pressure Gauge, 1/8" NPT Male Fitting, 1.5 Inch Dial for Automotive Engines - 15633 - Image 3](https://m.media-amazon.com/images/I/71sy977gy+L.jpg) ![Fuel Pressure Gauge 0-100 PSI - Liquid Filled Inline Fuel Pressure Gauge, 1/8" NPT Male Fitting, 1.5 Inch Dial for Automotive Engines - 15633 - Image 4](https://m.media-amazon.com/images/I/71CR7guuyHL.jpg) ![Fuel Pressure Gauge 0-100 PSI - Liquid Filled Inline Fuel Pressure Gauge, 1/8" NPT Male Fitting, 1.5 Inch Dial for Automotive Engines - 15633 - Image 5](https://m.media-amazon.com/images/I/818+jvyCEuL.jpg) ## Questions & Answers **Q: Does this come with any documentation or identification of any kind?

The original schrader valve would not let me use my existing fuel press. test gauge. As always, Amazon came through with the best price, FREE and FAST shipping. The gauge was super easy to install and I had an accurate read on my fuel press. in about 5 minutes. The gauge is easy to read and is not liquid filled. The gauge screws in to a 1/8 NPT threaded hole which is what a lot of EFI applications utilize for the pressure port. I had seen other gauges from the usual race catalog companies for under $20 but for $26 shipped how can you go wrong with a true name brand part?
