Great for troubleshooting more than just fuel pump relays. Work anywhere a relay is used. Just be aware of the current draw on the system so that the switch can handle it. Wish the big relay had a heavier switch. That size relay is rated up to 70a in some systems but the switch is only rated at 20a.

Great product to cut circuit testing in half. I diagnose A/C compressors, fans , fuel pumps and anything with a relay. Worst thing is the box but fits nice in case with other diag equipment....

Makes quick work of finding which relay is bad and if you have a bad relay you can bypass it and limp your vehicle back into the garage. Had a ignition relay go bad while parked out on the side street. Popped in the switch bypass and started the car up and drove back into the garage. You never know when relays are going to fail. Another good item to have in your tool box.

I used to take the cover of of relays and actuate them manually,well after breaking the covers to many times and the need to actuate more than one I bought this, had a no crank no start after an accident car got towed in,used it on the fuel pump and starter at the same time with the key in the ignition for immobilizer and fired right up,took 5 min to find the problem and saved me hours of tracing wires and diagrams.

Awesome tool to diagnose electrical systems on vehicles. These are for more than just fuel pumps. I use them for headlight switches, A/C compressors, and anything else that uses a relay on a car.

These work well and save time when diagnosing circuits. You can test the load side of a circuit as well as the component in question and eliminate that side of the circuit.

Great for bypassing relays and not having to run around trying to find a cotter pin or a piece of wire to do the job. Looks more professional from customers point of view.

These are great. Have got me out of many jams. Highly recommend.
