Will fuel pour?
I'm replacing the rear fuel pump and want to know what to expect with the fuel lines. I read in Wayne's book to empty the gas tank before disconnecting a fuel pump. In this case, he is talking about a 911's single pump.
My question is do I need to empty the tank or is there another way to control fuel from pouring out?

Although, I have never messed with mine, I would jack the rear of the car so the fuel has a chance to run towards the tank.
How much will come out? I don't know for sure, but there will definitely be some.

You can always disconnect the fuel line at the filter or accumuulator, place the gas line in a hose, start the pumps and drain it into a gas can. If you drive it to get rid of some, that keeps you from having lots of gas cans.
Also, you might be able to pinch the incoming line to the rear pump with needle nose vice grips. |

I pinched the line on mine, and barely spilled any fuel. Just make sure when you disconnect the line completely you have the other fitting handy to replace quickly. Also is good to put a cloth or something in the vice grip so as to not damage the hose. Really pretty easy job.

Thanks for all the good advice and now I feel better about pinching the lines.

I just replaced the rear fuel pump on my car. There's not much fuel that spills, maybe a few ounces from the line up to the motor.

No fuel will not flow past the stationary rollers in the front fuel pump so there is no spillage from the gas tank at all.
I've changed the rear pump and there is no fuel spillage anywhere, just a little tiny dribble of fuel in the line going up to the accumulator. Pinching off 20-35 year old rubber fuel lines is a real bad idea... especially when there is no reason to do that. |
