I'm making some modifications to my Endeavor to save on fuel costs. I'm going to install a fuel heater, but I'm getting stuck on the process of releasing the fuel pressure. The only guidance I've been able to find is to remove the "Circuit Relay" once you've started the engine and it will subsequently stall - therefore, empty fuel line.
Only I can't find anything that's labeled "Circuit Relay"!
Nothing that indicates fuel pump either. Please help.
Thanks.
