Fuel Filter and Clearing Out the Fuel Line

[jwalk1a]

I'm looking to replace my 95 Park Ave fuel filter and I want little or no gasoline spray/spillage when I'm changing it out.

Therefore, correct me if I'm wrong but I first relieve the pressure in the gas tank by removing the gas cap. Then, I have to disable the fuel pump by removing the fuse. I turn over the engine to use up the remaining fuel in the fuel line until the engine ceases. Wait a few seconds and try starting it again to use up any remaining fuel.

Is my approach correct?

How long is it supposed to take the now started car to use up the fuel in the line before it cuts out? I've already tried and I waited for what seems like an eternity without the vehicle cutting out. I feel like the fuse I removed is not the correct one for the fuel pump and that gas is continuing to be fed into the engine from the fuel line. The problem is the closest label I can find to the fuel pump is in the relays under the hood -- an orange fuse marked Pump. Is the gas cap supposed to remain off while the car is started/running?

Iv'e replaced a few and haven't had to do what your saying,there was a little residual pressure and then just changed the filter.

You can relieve the pressure at the fitting on the engine fuel rail if the engine is cold. Use a rag to catch the fuel and press the needle valve in the fitting. (Just like a tire valve).

No matter what you do, You will have spillage, No way around it. Pressure or no pressure what is in the lines will leak out. Sorry for the bad news, but its inevitable.

if you disable the fuel pump,the fuel will never come out of the fuel line.the motor has no capability to*suck* the fuel from the line.Expect fuel to get on the ground,and possibly on yourself,depending on where it is,and how the lines attach.

The bottle line is, Fuel will be spilled on thsi car. The top rails will drain out and the horizontal line will as well, plus the fuel in the filter itself. Forget about droppless fuel.. its not going to happen.

some lines themselves hold close to a gallon of fuel

Since my first post, I ended up replacing the fuel filter before driving from Orlando to Atlanta and back. I ended up getting around 33 miles/gallon highway!

...and yes I got soaked in fuel...

but I forgot to put on the o-rings. Do you think I need to put them on? So far I can't detect any fuel leaks.

What o-rings? There is only the lock snaps in the filter, which hopefully are on there, and should be cause the lines would blow off. if in fact those are not on there, get them on there immediatly.. You can get in a serious fire if you done. Fuel on hot pipes, bad mix!

if you didnt put a seal,and it requires it,you could have an early 4th of july if you arent careful

One side is a snap connector and the other side is a screw-on with a bolt. I found two o-rings in a baggy and guessed it was for the fuel filter on the bolt side, although I think I could get away using just one. Car is not on fire just yet. . .
