Well, I went and did it today! Put the Supra pump in the old National. I ran into a few problems, and I'll share. My car has a Spectre replacement tank with the metal dog dish at the bottom. I also used a Spectre hanger assembly that I refitted with the Racetronix harness. The replacement hanger and pump is a no go through the hole in the Spectre tank. I would have had to bend the tank lip, as I was in need of about 1/16 clearance that I did not have. What I did instead is work on the hanger. I had removed the lower support, and just hose clamped the pump to the hanger at the correct height. The solution is to re angle the fuel sender, as it is the part that will not fit through the hole. You need to take a Dremel to the backing plate that the sender attaches to. Make a shallow groove along the backside at the hanger itself, and just fold the sender plate inboard, moving the float towards the sock filter. There is sufficient room to angle the sock outboard somewhat, and then angle the float up close to the sock. Presto, now its a drop in deal! Like others, I had to readjust idle fuel pressure, backing it down about 5 psi to get back to specs. Not a big job, just take your time and think it out. Thanks, Counterman.
