Carb Fuel Pressure Gauge
Carb fuel pressure gauge is located in the high-performance racing and classic car repair market, and is the core monitoring tool to ensure the stability of the carburetor fuel supply system. The product uses a precision bellows or spring tube structure, specifically for the carburetor low pressure environment (usually 0-15 PSI) range optimization. The shell is made of 304 stainless steel and filled with high-performance silicone oil, which can effectively resist the severe vibration of the engine compartment and ensure the smooth and accurate reading of the pointer. Its compact structure, standard 1/8 NPT standard threaded interface, both corrosion resistance and installation convenience. In terms of design, the pressure gauge pursues excellent economic benefits and long-term life. The use of high-visibility fluorescent dials and anti-fogging tempered glass not only improves the clarity of readings in extreme environments, but also significantly reduces the risk of engine knock or cylinder flooding caused by abnormal fuel supply pressure. Whether it is used in passenger car modification, lawn mowers and other garden machinery, or complex industrial fuel pump testing, the product can show excellent environmental adaptability. Its various material versions (such as 316L stainless steel isolation diaphragm) support special media such as alcohol fuel (E85) to meet the ultimate pursuit of reliability.
Carb Fuel Pressure Gauge Characteristics

Precise range designed for carburetor
with a narrow range design of 0-15 PSI (1 BAR), the measurement accuracy can reach ± 1.5% of full scale. Compared with ordinary high-pressure meter, it can more sensitively capture the subtle pressure fluctuations 0.5 PSI, ensuring that the carburetor needle valve always works under the ideal pressure.

Hydraulic damping seismic technology
The instrument panel is filled with high-purity anti-wear silicone oil, which can absorb the high-frequency vibration generated by the engine. This reduces the pointer volatility by more than 90%, which not only protects the internal gear mechanism from wear, but also allows the driver to obtain stable readings during intense driving.

High temperature resistant all-metal sealing structure
The shell is made of 304 stainless steel and combined with seamless welding process, which can work for a long time in the engine compartment environment up to 120°C. This structure eliminates the risk of leakage caused by high temperature aging of the plastic shell, and extends the service life of the product by 2-3 times.

Compatible with E85 and a variety of alternative fuels
The internal sensing element is specially nickel-plated for extreme corrosion resistance. Even if it is soaked in fuel containing 85% ethanol, its diaphragm will not oxidize or deform, making it an ideal choice for modern modified vehicles to use environmentally friendly fuels.

Humanized pressure relief compensation design
The top is equipped with a unique oil-filling hole rubber plug pressure relief valve. Aiming at the problem of internal pressure accumulation caused by the increase of ambient temperature, the internal and external pressure balance can be realized only by manual operation, and the zero drift error caused by the ambient temperature difference can be completely eliminated.

Standardized tool-free maintenance interface
Uniform industrial-grade 1/8-inch NPT connectors are used and precision thread ground. The zero-leakage connection can be achieved without the use of sealing tape during installation, which greatly shortens the system debugging time and supports quick disassembly and assembly on various fuel distributors.
