Value Collection TU-448-PB Fuel Injection Pressure Tester

Product Description

The VALUE COLLECTION TU-448-PB is a mechanical fuel injection pressure tester designed for diagnosing fuel delivery systems on gasoline-powered vehicles. The gauge reads from 0 to 100 psi with 1 psi graduations, giving technicians a direct, reliable readout of fuel rail and line pressure without the need for electronic diagnostic tools. The tester features a steel construction throughout and connects via a 16-inch hose, providing enough reach to route from the engine bay to a visible position during live testing. This tool is suited for automotive service professionals performing fuel system diagnostics on port-injected and throttle-body-injected engines.

This tester is used in automotive shop and field service environments where technicians need to verify fuel pressure against manufacturer specifications, identify weak fuel pumps, clogged filters, faulty pressure regulators, or injector leakdown. The 16-inch hose length accommodates a range of underhood layouts, making it practical for both domestic and import vehicle applications. The analog gauge format provides an immediate pressure reading without powering on external equipment, useful for quick diagnosis during busy service workflows.

Key Features

• Pressure range of 0 to 100 psi covers typical fuel injection system test requirements
• 1 psi graduation scale for accurate, easy-to-read pressure measurement
• 16-inch hose length provides flexibility for routing during live engine testing
• Steel construction throughout for durability in shop environments
• Mechanical analog gauge requires no batteries or external power source

Compatibility

Designed as a general-purpose fuel injection pressure tester compatible with a wide range of gasoline-powered vehicles equipped with port fuel injection or throttle-body injection systems.

Installation Notes

This tester is typically used by automotive technicians performing fuel system diagnostics. Before connecting the tester, relieve residual fuel system pressure according to the vehicle service manual and ensure the ignition is off. Use appropriate fuel-rated fittings and adapters to connect the tester to the fuel rail Schrader valve or inline test port. Follow all applicable fire safety precautions when working with fuel systems, and avoid testing near open flames or ignition sources.
