Put a full coverage fuel system service kit in your toolbox and greater service opportunities in your shop!

The 6550PRO from OTC comes with an analog fuel pressure gauge preferred by professional service technicians giving precise pressure readings as well as a view of pressure sweeps during the testing analysis.

The pressure testing manifold is designed with a bypass valve letting the technician perform basic fuel flow assessments.

The 6550PRO has more adapters than any other kit we’ve found giving the best coverage of any kit on the market. Domestic, Asian and European – we’ve got ‘em! Each adapter in the 6550PRO works with Schrader valve fittings to ensure 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 from OTC 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.

Every 6550PRO comes with an Application Manual (6550MAN-08) showing technical references for Make/Model/Year, Engine for vehicles produced between 1997 and 2008 – inclusive. We include Fuel Injection system, OE Fuel Pressure ranges, Fuel Pump Access point and disabling reference, OTC adapter reference and fuel line access locations for virtually FULL VEHICLE COVERAGE.

• 0 – 100 PSI Fuel Pressure Gauge
• 47 OTC fuel injection system adapters each with a quick connect Schrader Valve
