When I get to the fuel tank I'm going to look at that pump and see if there is an alternate. It'll be several days before I get to that end of the car.
Here's a shot of the original motor with the front chopped out. I drilled all the tabs prior to using the zipwheel so I can just put it back up and bolt it in. I have no idea how anyone could get the engine out without doing this, maybe they took it out the bottom.
