Doin my plenum today, got everything off except the fuel line. I was gonna leave the injectors and rail intact to the manifold and just pull the line off. I know i need a fuel disconnect tool( 3/8 right?) I pulled the relay and tried to start the truck to let it die but the truck wouldnt start after i pulled it. I pulled the relay not the 40 or 50 amp fuse or whatever was that right? How can i verify theres no pressure? I just didnt want to use the disconnect tool and have gas spraying all over. trucks a 97 5.9 thanks

 

or should i leave the line on and take the 4 bolts off and pull the injector, rail and line as one? Ive searched on this but am not sure what is the best/easiest way to do it.

 

I think there is a fuel rail pressure test port on the side of the driver side rail....looks sort of like a valve stem on a tire. push that in and it should relieve all the pressure but a little bit of the fuel may fly out....

 

thank you, i will look for it and maybe put a rag around it so gas doesn't get all over. I think im gonna just leave the injector and rails on the intake and just pull the line

 

Just pull the line and leave the rails and injectors. Makes a nice handle to get that monster out of there.

 

It's a 97 with a plastic fuel rail correct? No test port. And IIRC, you don't need a tool to disconnect the fuel line. In any event, I hope you have the battery disconnected? This way it doesn't matter if fuel sprays out. Just make sure you use a rag over the connector so gas doesn't get in your eyes.

 

Yea i didnt find a test port, battery is disconnected, how do i get the fuel line off with out a tool? ill go check if its plastic or not but i think so

 

yea its plastic

 

Does it look like this? And please tell me you are not doing the work without a Haynes and the free FSM from the FAQ/DIY section.

 

yea thats what it looks like. I have the fsm on the computer.
