 Posted: Tue Oct 16, 2007 2:49 am Post subject: How to drain fuel tank in 1999 Caddy |
 |
|
I have a '99 DeVille that blew a head gasket. I plan on junking the
car, but before I have someone haul it off, I want to drain the $50 of
gas out of the tank.
There appears to be a check valve at the bottom of the filler tube at
the tank entrance. This is very effective in stopping me from simply
putting a tube down into the tank.
My factory shop manual shows a "special" drain tube but they don't
specify if it goes in the tank or maybe attaches to the fuel line from
the tank to the engine. They simply say "Drain the tank."
Bottom line: Has anyone actually drained a tank successfully? If
so, exactly how?
There must be a way to accomplish this because shops must need to
drain tanks prior to a tank replacement.
Driving the car until the fuel is used is not an option.
If I disconnect the fuel line from the filter which is close to the
tank, will the fuel pump run continuously with the key on or will the
engine computer shut down the pump if the engine isn't running?
TIA, Rich |

The fuel pump will run continuously if you pull the fuel pump relay and
jumper the socket where the relay contacts are. |

If your junking it, take an awl and hammer a poke a hole in the ***
thing and be done with it. |
