The 1.5in Gauge 0-100 PSI Liquid Filled from ALLSTAR PERFORMANCE is a compact mechanical pressure gauge built for engine builders, racers, and anyone running a tight dash or panel where space is limited. It reads from 0 to 100 PSI across a 1.5-inch white face inside a silver case, a range that covers most fuel and oil pressure jobs on carbureted and injected setups. The liquid-filled construction dampens needle vibration so you can read pressure cleanly while the engine runs. It's a no-nonsense gauge for builders who want accurate numbers without paying for a full digital cluster.
Liquid filling is the feature that separates this gauge from a dry-movement unit. The glycerin fill cushions the internal movement and slows needle bounce under engine harmonics and chassis vibration, which keeps the reading steady when a dry gauge would flutter. The 1.5-inch dial size, listed at 2.5 inches in overall length per manufacturer specifications, fits the smaller mounting cups and panels common to drag and circle-track builds. The white face with black graduations gives high contrast for quick reads in daylight or under panel lighting. Pair it with the right sender and line, and you have a low-cost monitoring solution that holds up to the heat and shake of a working engine bay. Browse our oil pressure senders to complete the install.
Builders reach for this gauge when monitoring fuel pressure on a regulated system or keeping an eye on oil pressure on a race or street motor. It mounts cleanly in a single-gauge cup or alongside others in a multi-gauge panel, and the 0-100 PSI window suits most pump-fed fuel and wet-sump oil applications. If you're outfitting a dash from scratch, look at our full lineup of individual gauges and matching fuel pressure gauges to keep the readouts consistent across the panel.
The liquid fill, typically glycerin, surrounds the internal movement and dampens needle vibration. On a running engine, a dry gauge needle can bounce and flutter from harmonics and chassis shake. The fluid steadies the needle so you can read pressure accurately while the motor is under load.
Yes. The 0-100 PSI range covers most pump-fed fuel systems and wet-sump oil pressure applications. You'll need the correct sender and line for your setup. Confirm your system's pressure stays within the 0-100 PSI window before mounting.
This is a 1.5-inch dial gauge, so it fits 1.5-inch mounting cups and panels. It's smaller than the common 2-1/16 and 2-5/8 inch gauges, which makes it useful for tight dashes and limited panel space.
No. The gauge is a standalone mechanical unit. You'll need to add a compatible pressure sender and the appropriate fittings and line for your application.
