0-40 Liquid Head Only

The 0-40 Liquid Head Only from QUICKCAR RACING PRODUCTS is a precision tire pressure gauge replacement head designed for serious racers, fabricators, and automotive enthusiasts who demand accuracy in their inflation systems. This liquid-filled gauge head serves as the critical sensing component in tire pressure monitoring setups, making it essential for anyone building custom fuel systems, race car platforms, or modifying vehicle suspension and braking architecture. The 0–40 psi range covers most street and competition applications, from low-pressure off-road setups to high-performance road racing configurations.

Liquid-filled gauge heads eliminate needle flutter and vibration that plague dry-dial designs, particularly in high-vibration environments like engine bays and chassis-mounted fuel systems. The fluid damping ensures stable, readable pressure values even under constant movement and thermal cycling, critical when tuning fuel delivery systems or monitoring tire dynamics during acceleration and braking events. QUICKCAR's gauge head is engineered as a replaceable cartridge, allowing users to swap sensing elements without replacing the entire gauge assembly—a practical advantage for long-term shop use and prototype development where multiple pressure ranges may be needed across different builds.

This replacement head benefits engine builders, fuel system fabricators, and race car mechanics who integrate QUICKCAR gauge panels into custom instrument clusters and fuel cell monitoring systems. Its compact footprint (2.9 × 1.5 × 3.55 inches) and lightweight design (0.43 lbs) make it ideal for space-constrained applications such as cockpit-mounted fuel pressure displays or underhood system monitoring arrays. Whether you're diagnosing fuel delivery issues, validating pump output during a dyno session, or building a complete custom gauge setup, the 0–40 Liquid Head Only delivers the reliability and repeatability that serious automotive modification demands.
