FAQ
Should fuel pressure gauges be liquid filled?
- Yes, using a liquid-filled fuel pressure gauge is recommended. The liquid filling helps dampen vibrations and pulsations, providing more accurate and stable readings, especially in high-vibration environments.
Why are some pressure gauges filled with fluid?
- Pressure gauges are filled with fluid (usually glycerin or silicone oil) to reduce needle vibration, enhance shock resistance, and improve overall accuracy. This is particularly beneficial in applications where vibrations or pulsations are common.
What is the filling liquid for a pressure gauge?
- The filling liquid for pressure gauges is typically glycerin or silicone oil. These liquids help stabilize the gauge's needle movement, ensuring more precise and reliable pressure readings.
What is the difference between liquid filled and non-liquid filled pressure gauges?
- Liquid-filled pressure gauges have a damping liquid inside that minimizes needle oscillations for improved accuracy and durability, especially in high-vibration environments. Non-liquid-filled gauges lack this fluid, making them more susceptible to vibrations and providing less stability in readings.

Motor Vehicles
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.
Tools:
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.
