Default Replacing rubber fuel line?

I need to replace the rubber fuel line that goes from the metal line of the fuel tank to the fuel filter. This rubber line is about 6" in length. It's located on the passenger side, under the rocker panel, near the front fender. My question is...how do I replace this rubber line without losing a lot of fuel? I certainly can't pinch the metal line shut before removing the rubber one.

well use as much fuel up as possible and jack up the front of the car.....and use big wire cutters and cut the line off of the fuel pump first and plug it immediately.......then put the new line on the fuel pump and cut the old line off the metal line with a razor blade and really quickly make the swap....



i bet you could blow some low pressure air into the supply line and that would stop any siphon action

Clamp the rubber line at the tank connection at the rear of the car

clamp the rubber line and then remove it from the pump. cut the new line to length and put it on the pump side, have the new clamp ready on the new line and then swap the old and new quick, a little fuel will leak but there's not much you can do about that

Gas is so expensive now so I can't afford to lose a drop.

My vette is an '82 with an electric fuel pump in the tank.

Use a Oaklahoma "credit card" and drain the tank before working on the fuel line or be prepared to get wet.

Reminds me of that old saying, "Last time I crossed into Oklahoma the kids wanted to fight, the wife wanted sex and I had the urge to steal." Of course I'm sure Oklahoman's had a lot of kind things to say about us flatlanders from Kansas as well.

Wouldn't I lose just the fuel that's already in the line and not the tank because the electric pump would act as a stopper?

Make sure when you cut your new replacement line you cut it just long enough so it does not cause a restriction when it bends to go to the pump. Ecklers sells precut and bent replacement lines to avoid this problem. Just a heads up.

I changed my mechanical fuel pump last week and surprisingly didn't loose that much maybe 1/2 cup with the fuel tank half full and the front end on ramps. Your electric pump should prevent the fuel to go anywhere. Just use a little cup to catch the fuel that is already in your rubber hoses and don’t forget to wear safety goggle!

When I did this I used a standard straight fuel line that I bent to fit, I then had all kinds of fuel starvation problems, I finally found that during max fuel pressure (high speeds) that the line would collapse and starve my carb. The correct replacement is a "S" shaped line that you can get at Ecklers or other online parts stores. Peace.

put a small bucket or pan under where you are working on the hose.on a 82 you can start up the car then pull the fuse for the fuel pump.

That's what I do. Wrap a rag around the line and clamp "gently" (so as not to permanently crush) with vise grips.
