Professional Master Fuel Injection Service Kit

The OTC Professional Fuel Injection Master Fitting Kit offers a comprehensive fuel system service kit, providing greater service opportunities in your shop. This kit from OTC comes equipped with an analog fuel pressure gauge, preferred by professional service technicians, which delivers precise pressure readings and enables the visualization of pressure sweeps during the testing analysis. The pressure testing manifold is designed with a bypass valve, allowing the technician to perform basic fuel flow assessments.

The 6550PRO kit boasts more adapters than any other kit on the market, ensuring the best coverage for domestic, Asian, and European vehicles. Each adapter works with Schrader valve fittings, enhancing user safety by preventing fuel spray when connecting or disconnecting the pressure gauge (included), the fuel line, or an accessory like a cleaning canister.

All seals and O-rings in the 6550PRO kit are made with highly durable Viton material to prevent swelling or cracking when exposed to gasoline, alcohol blends, and even the most aggressive injector cleaning chemicals. The kit comes with an application manual that provides technical references for make, model, and year of vehicles produced between 1997 and 2008, inclusive. The manual includes information on fuel injection systems, OE fuel pressure ranges, fuel pump access points and disabling references, OTC adapter references, and fuel line access locations, ensuring virtually full vehicle coverage.

This comprehensive kit allows technicians to perform a variety of essential fuel system diagnostics, including fuel pressure testing, weak fuel pump identification, restricted filter testing, fuel flow analysis, and leak-down tests. The kit includes a 0-100 pounds per square inch fuel pressure gauge, 47 OTC fuel injection system adapters, each with a quick-connect Schrader valve, and a replacement seal kit for convenient maintenance.
