Actron Fuel Pressure Tester Kit for Throttle Body Injection System CP7817 Sealed
The Actron Fuel Pressure Tester Kit CP7817 is an engine diagnostic tool specifically built to safely test fuel system pressure on Throttle Body Injection (TBI) systems. It helps you diagnose drivability problems caused by out-of-spec pressure, such as a faulty fuel pump, failing pressure regulator, leaky injectors or clogged fuel lines. Key Specifications
- Pressure Range: 0 to 60 PSI, featuring a full-sweep, easy-to-read mechanical gauge.
- Hose & Fittings: Includes a 36-inch flexible connection hose paired with solid brass fittings.
- Special Adapter: Comes with an M16 x 1.5 threaded line fitting adapter specifically for GM TBI systems that lack a standard fuel access valve test port.
- Safety Feature: Features an integrated pressure relief valve to cleanly and safely drain fuel pressure after completing your test.
Vehicle Compatibility & Restrictions
- Ideal Use: Designed for older electronic fuel injection layouts, specifically GM TBI setups (such as classic late-80s to mid-90s Chevy/GMC trucks and cars).
- Critical Restrictions: DO NOT use the CP7817 kit on diesel engines or flex-fuel (E85) vehicles.
Basic Diagnostic Steps
- Prepare: Park in a well-ventilated space, wear proper eye protection and gloves and let the engine fully cool down.
- Connect: Tap into the fuel line using the included GM TBI adapter fitting (typically placed at the fuel filter connection or the throttle body inlet).
- Prime: Turn the vehicle ignition switch to the "Run" position without cranking the engine to prime the system.
- Read: Check the gauge reading against your vehicle's factory specifications. Leave it for 5 to 10 minutes to verify if the system holds steady residual pressure.
- Relieve: Use the integrated relief valve button to safely drain the pressurized gasoline out of the tool into an approved container before disconnecting the lines.
