JEGS 555-41010 Fuel Pressure Gauge Features:
- 0-15 psi reading for most carbureted applications
- 1/8 in. NPT male threaded fitting to screw into your existing fuel system
- Liquid-filled to slow down engine vibration of the needle
- Stainless steel case and bezel for long life and great looks
- 1 1/2 in. diameter black face for compact viewing such as under the hood
Should fuel pressure gauges be liquid filled?
- Yes, liquid-filled fuel pressure gauges dampen vibration, prolonging gauge life by preventing internal components' wear and tear, ensuring accurate readings.
Why are some pressure gauges filled with fluid?
- Fluid-filled pressure gauges absorb shock, reducing needle movement caused by vibration, maintaining accuracy, and enhancing durability.
What is the filling liquid for a pressure gauge?
- The filling liquid for pressure gauges is typically glycerin or silicone oil, chosen for its stability and resistance to temperature changes.
What is the difference between liquid filled and non-liquid filled pressure gauges?
- Liquid-filled gauges have fluid inside, reducing vibration for accuracy and durability, whereas non-liquid filled gauges lack this damping, making them more susceptible to movement and wear.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
