Rachel,
I'm not getting a lot of resistance at all. It really does feel like
the pump gears are spinning and sucking air. I've checked and
rechecked and am 99% sure the socket is seated correctly--although I
do have to admit it is pretty much impossible to see with my own eyes.
I have a spare pump, and I'm checked and double checked that I'm not
turning it backwards. But, heck, if I still can't prime it after
spinning for a few minutes, I'll try reverse just for the heck of
it... ;-)
I don't think the pump itself is, in fact, submerged. I'm speaking
of the geared part of the pump. Clearly, the business (bottom) end
of the pump pickup tube is submerged in the oil in the sump, but
remember this is a diesel, which is an I-4 tilted 55 degrees on its
side. The tube is 6 - 8 inches long and descends at, what, a 30
degree angle or so? I'd have to guess the pump is in the range of
1-3 inches above the surface of the oil in the pan. I think my
problem is I have to pull the oil up that tube.
Aaargh!
