Engine Mechanical problem
1999 Volvo S70 Front Wheel Drive Automatic

I am replacing the air box in my 1999 S70 2.4L engine. I cannot figure out how to disconnect the fuel line that loops through the intake manifold so I can move the manifold out of the way to replace the air box.

Sorry, my software just says "disconnect fuel lines" doesnt say anything about a specific tool. Any chance of getting a picture? Most cars use a sleeve type disconnect tool, this is most likely what you need, it slide on thefuel line an dslips into tehconnector to retract the teeth inside that hold it. You can rent/purchase these for very cheap at just about any parts store
