Fuel Pressure Sender

The AutoMeter Fuel Pressure Sender (Model 2239) is a precision mechanical instrument designed for vehicles equipped with full-sweep fuel pressure gauges requiring direct tank or fuel line monitoring. This pressure sending unit bridges your fuel system and analog gauge cluster, converting actual fuel rail or tank pressure into a proportional electrical signal that drives needle movement across the gauge face. Whether you're diagnosing fuel delivery issues on a classic muscle car, tuning a modern performance engine, or maintaining fleet vehicles, this sender delivers real-time pressure feedback essential for engine health and performance validation.

This fuel pressure sender utilizes a 1/8-inch NPT male threaded connection for secure installation into fuel lines, fuel rails, or tank fittings without adapter complexity. The unit measures pressure across a 0–30 psi range, making it ideal for carburetor-fed systems, fuel-injected street engines, and naturally aspirated powerplants where factory or mild boost pressures remain within this envelope. The sender's full-sweep design ensures smooth, linear gauge response across the entire pressure band, eliminating dead zones and providing mechanics and enthusiasts with accurate, readable data for fuel system diagnostics, carburetor tuning verification, and fuel pump performance assessment.

Installation pairs this sender with any AutoMeter full-sweep fuel pressure gauge calibrated for 0–30 psi operation, ensuring matched impedance and linear output across the entire scale. Technicians favor this configuration for naturally aspirated engines, street rods, and vintage vehicle restorations where analog instrumentation is preferred or required. The compact, lightweight design (0.14 lbs) minimizes weight and complexity in engine bays. Verify gauge compatibility and fuel line pressure rating before purchase; this sender is engineered for gravity-fed and mechanical fuel pump systems as well as low-pressure electric pumps, making it a versatile diagnostic and upgrade component for fuel system transparency.
