Star Products Fuel Injector Tester
Star Products Fuel Injector Testers: Professional-Grade Diagnosis
When a vehicle's engine runs rough, struggles to start, or delivers poor fuel economy, an accurate fuel system diagnosis is essential — and that's exactly where Star Products has built a long-standing reputation. Operating under the Lang Tools umbrella, Star Products has earned the trust of professional technicians by delivering durable, reliable, and purpose-built automotive testing equipment. Their fuel injector testers are a prime example: engineered for the shop environment, not the driveway hobbyist.
Comprehensive Coverage Across Domestic & Import Vehicles
One of the defining strengths of Star Products fuel injector testers is their broad vehicle compatibility. Their lineup is designed to cover a wide range of fuel injection systems found on both domestic and import platforms. The TU-113PB Fuel Injection Tester is built to work with American Motors, Chrysler Corp., Ford Motor Co., GM systems, and a variety of Japanese fuel injection platforms. It also works with systems using Bendix-type fuel injection or Schrader-type valves, including the small Schrader valve found on both T.B.I. and Multi-Port Fuel Injection systems on Ford products.
For shops needing maximum coverage, the TU-443 Deluxe Global Fuel Injection Pressure Test Set takes things further. The many adapters, hoses, and fittings cover most fuel injection systems worldwide. Its 3½" gauge features a dual-scale dial with ranges from 0–100 PSI and 0–7 bar. A built-in relief valve and extended tubing allow technicians to safely vent fuel pressure, while the 4-foot gauge hose and gauge with a hook can be hung up to free the technician's hands.
Master Kits for the Full-Service Shop
For professional shops handling a broad range of makes and models, Star Products also offers master-level kits like the TU-550. It covers most models from 1988 through 2004 and includes the five most popular banjo bolt test adapters — M14 x 1.50, M12 x 1.50, M12 x 1.25, M10 x 1.00, and M8 x 1.00. The test gauge assembly disconnects from the test hose and valve assembly for easier storage and improved gauge protection. Longer redesigned test hose adapters for Ford, Toyota/Geo, and Audi/VW allow the adapters to tee into the fuel system with less distortion and movement of the fuel line.
More Than Just Pressure Testing
Star Products fuel injector testers do more than measure pressure. These testers determine if the fuel pressure regulator needs adjusting or replacing, and come in a heavy vinyl pouch with instructions and specifications. They also identify if other components are bad — such as the fuel pump or filter — and reveal whether the pressure regulator can be adjusted to the correct setting.
The Star Products lineup includes fuel pressure testers, fuel injection cleaning canisters, back pressure testers, and compression testers for diesel, gas, and small engines — making them a comprehensive solution for any diagnostic bay. Whether you are chasing a lean condition, verifying injector pulse, or confirming rail pressure after a repair, Star Products provides the tools to do the job right.
