I was under the car today looking at the hard lines that run from the pump to and from the engine. Both lines are disconnected while I wait for a new pump to arrive.
The return line had some semi-dry gasoline sludge in it so I got the bright idea to connect an air line at the engine end to blow the lines clean. Good plan with bad execution. Two mistakes:
1) I got the lines mixed up.
2) Did not put a catch container at the other end.

The only line I had disconnected in the engine bay was at the fuel filter so I hooked an airline to it and set the regulator for 15 PSI. I gave it a shot of air, and heard interesting noises from underneath the car. The floor was now covered with about a 1/2 cup of gasoline which I quickly wiped up. No lights were underneath and I did have the fire extinguisher and garden hose nearby. Whew.

Because the return line had no liquid in it, I was not expecting anything other than sludge to some out. But blowing on the fuel filter line does not put pressure on the return. Dumb dumb dumb. I did not think that through.

On the bright side, I now know I have or will have clean passage of gas right from tank to filter so that's a good start. Next I need to figure out a good connection point to put air into the return line from the engine bay. I have looked, but I cannot trace the path of the return after it leaves the front of the engine bay. Anyone know of a good, easily accessible connection point?
