Relay Bypass Switch Set No. 9036

The IPA Relay Bypass Set (No. 9036) is a first-time tool that plugs in place of a vehicle's fuel pump relay providing direct control over the fuel pump circuit. When testing fuel injection systems, the Relay Bypass allows actuation of the fuel pump when the engine is not running. The 3-pc set covers the most common domestic and Japanese applications, along with popular German models. The Relay Bypass Set acts as an on/off switch that plugs in place of the most common relays. They are simple-to-use and help to troubleshoot fuel system and electrical problems.
