OK, I managed to jack up the left side of the bed enough to check things
out and get some pictures. I don't think I have enough room to get the
pump out of there, though. I still think the bed needs to come clear off.

There are four things going to the top of the pump: 1. electrical, 2.
fuel supply, 3. filler vent and 4... I'm assuming that goes to the evap
canister? I didn't follow it all the way up, I can probably do that if
necessary. The picture is here (items I mentioned are right to left on
the picture):

So, assuming that last connection really is for the evap, that would
mean that this is a returnless setup.

I also tested the voltage right on the electrical connector. It
definitely gets 12V. It only gets turned on for a couple of seconds
after I turn the key on, but this matches what it says in the FSM. I
still don't hear the pump turning. A bit of buzzing, but it sounds more
like a frozen electrical motor.
