Default Question regarding Fuel Pressure and Replacing Fuel Lines

So I will start replacing Fuel Injection hoses soon. Plan on doing all of it from trunk to front.

I have seen a video on doing the ones in the trunk and so I will be prepared for the quantity of gasoline coming out when the hoses are disconnected. What I don't know is HOW MUCH gas will come out of the hoses in the engine bay when the hoses are disconnected. I have gas line clamps that I can use on longer lines.

Just would like a idea of whether I am going to see a little leakage, a trickle or a steady stream.

The system hasn't been energized in about two weeks so I would think the pressure in the system would have bled off, but I haven't done this before.

At the trunk end of things it'll be a gusher of gas when you remove the tank-to-changeover hoses so, while no need to panic, be prepared to work very quickly.

Buy some 1/2" wooden dowel. You'll need a couple pieces, 4-5-6" long. Whittle or grind the ends to a taper.

When you remove the hoses that go from the tanks to the changeover valve, quickly insert the dowel into the hose. The tapered ends ensure you'll be able to do so very easily and quickly. There will still be spillage so put some old towels or rags under the area to soak it up.

Or.....drain the tanks first.

All the other sections of plumbing shouldn't be much of a problem. A few ounces of gas. As you open any particular section wrap a rag/towel around it. And, yes, the pressure will have bled off since you haven't used the car.

Cheers

or follow the Service Manual instructions and depressurize the fuel system.

also disconnect the battery as innstructed.

Fuel is explosive.
