I recently picked up a 73 1.7 that had been stored inside for 20 years. The body is great as expected sitting inside, but the fuel pump does not work among other things and looking for a replacement I see that they are no longer made. Great! Can I retrofit a later model pump to fit my car? I thought the injection systems were pretty much the same all the way through the years, but the newer pumps look vastly different from my hunk of metal pump, mine having 3 hose connections and the newer ones only the typical two. Thanks in advance.

Some folks might tell you to move the pump, but I won't be one of them. Too much plumbing and adapting, and (unless you pop for SS pipes) you'll be pressurizing lines that were designed to run at no pressure at all. Keeping the pump in the back means you'll need maybe a foot or 18" of 12mm hose, the adapter hose, the pump, and new rubber fuel lines from the pump area to the engine area.
IME, the stuff you read about vapor lock is hearsay and mostly unsupported by evidence. I live where it gets hot, and I used to live in La La Land, where it's hot AND there's a lot of slow traffic, and I've never seen a single case of it. Drain the tank, remove the filler neck and take a good look at the inside of the tank. If there's rust and/or crap in there, pull the tank, replace the hoses under there (some 7mm, some 9mm), and have the tank cleaned and coated. Be REALLY careful not to crimp the hoses when you reinstall everything. Get a new filter sock for the inside of the tank, too. Save the paper washers for the bottom fittings, they're hard to come by.
