My fuel pressure gauge is not working, whats wrong?
The fuel pressure sender relies on a ground at the threaded base. If you’re using our fuel pressure adapt or you have your sender connected to an aftermarket fuel rail or regulator chances are you need to ground the sender. The sender can be grounded by connecting a ground wire to the base or housing of the sender. This can be done by wrapping a wire around the fittings or the sender itself. You can get more fancy and drill / tap a ground screw into your system. Only do this if there is enough excess material to add a screw.
