Depressurizing fuel system
Depressurizing fuel system
Hey guys I gotta replace one of my injectors and I was wondering the best way to depressurize the system. Looking at all the relays and fuses I’m seeing nothing for a fuel pump. I tried pressing the shrader on the service valve and nothing came out. Hoping someone can help me so I don’t take a bath in e85

Re: Depressurizing fuel system
Make certain you're getting on the shrader valve tip and are moving it enough. If nothing comes out, your problems may be other than your injectors, unless one is leaking. If one IS leaking, the system will self-depressurize.

Re: Depressurizing fuel system
There is surprisingly not a lot of volume of fuel that comes out. Don't expect a gushing amount of fluid coming from the valve. It is intended to relieve pressure which bleeds down rather quickly. As Gene said, if you are not getting any, make sure you are depressing the valve. While you may not get a bunch of fuel from the valve, there's still a lot of fuel in the fuel rail ….you will see.
