yes - that's essentially what I was asking. Didn't see any reason in principle why I couldn't, but I've never actually done it. My ideal is pulling the hose off the bottom of the filter and giving the factory pump 12V and filling a container.

The car idles OK but has a bad shake and is super down on power, like it's running on about 60% fueling or 2-3 cylinders.

If you don't want to go electric, you can get siphon pumps at any autopart / auto tool store. I used to resurrect old cars, it has always been sufficient for me to pump out the tank and refill with new. Sometimes a bit of MMO would help with deposits on carbureted vehicles ... on FI, a can of FI cleaner ...

Thanks, that's a good idea I hadn't thought of.
Car is EFI (1993) so point taken on fuel system pressure. Also good reminder about damaging the pump by running it dry but I figure a few seconds wouldn't hurt it.
