It is designed for fuel injected systems. It features a relief button and 6-ft hose to safely dispose of gasoline without disconnecting the gauge. It also works on the throttle body injection with a threaded connection at fuel filter or throttle body. It is 2½" gauge with 0-100 psi/0-700 kPa scales for accurate measurements.

Check the Ford Specs for the proper fuel pump pressure. **Q: Does this work on 2000 silverado 1500 4.8 v8** A: Yes, the Actron CP7838 Pro Fuel Pressure Tester Kit can be used on a 2000 4.8L Chevy Silverado V8.

The coupling on the test hose in the CP7838 Fuel Pressure Tester Kit will connect directly to this Schrader test port. **Q: Does this work in a Honda civic 2002..?** A: No, the CP7838 Pro Fuel Pressure Tester Kit will not work on a 2002 Honda Civic. The Kit does not have the necessary connecting adapter for the Honda Civic. **Q: Will this work on a 4.6l northstar engine in a 95 cadillac eldorado?** A: Yes, the Actron CP7838 Fuel Pressure Tester will work on a 1995 Cadillac Eldorado with a 4.6l Northstar engine.
