Fuel tank drain...

How do you drain the fuel tank? I've tried to put a small hose down the filler pipe...Something stops it at the bottom of the neck (it seems).

Disconnect your hose at the fuel filter and jumper the fuel pump relay (103). Then let the pump do the heavy lifting.

Thanks...
The problem is that a line on top of the tank is leaking like crazy...hense the need for an empty tank for removal. Can your suggestion still work?

Is it leaking at the fuel pump connection, or the EVAP hose system connection?

Follow that hose! If it's the EVAP hose, just pumping most of it out should be fine. Stop it before it runs dry though.

The fuel pump location appears dry. The XC70's fuel pump "lid" is on an angle at the front of the tank facing the back of the rear seat. The leak is "piddling" off the top back of the tank. The fuel filter is about a foot away, so its not that. Could it be a line or the EVAP? Are these both near the rear of the tank?

You can disconnect the fuel rail and connect a pipe to a big drum, Just insert the key and the fuel pump will prime. It will pump all the fuel out the tank into your big drum in a few minutes. I should have done this a few days ago on my tank drop but I didn't have a big drum for the fuel.

Thanks Red Arrow...

You mention you did a tank drop...Do you have an XC70? If so, what was involved in doing that?
