I would like to depressure the fuel lines to replace gas filter. But I dont want to use the rail to depressurized the fuel system. I have the windshield fuel gauge hooked up to the rail, and its a pain in the ass to reconnect everything after if I use that area because of leaks. Can I start the car, pull the fuse and wait til it shuts off. Then system is depressurized , Which fuse?, the relay on the side fender?
