So I just finished replacing all of the rubber fuel lines in the back of the car. Not too bad- just no room to move around under there which was no surprise.
The Spica mechanical fuel injection pump stays cool with flowing fuel- so most of the gas is just being circulated back and forth from the fuel tank, with a little skimmed off to run the engine.
I bought new fuel line clamps as well for everything- but some of the ones I pulled off the car are excellent clamps so I just cleaned them up and reused them in a few locations.
Here are the new lines up above the rear axle coming out of the top of the fuel tank (the feed line is the larger -1/2" i.d.). The smaller is the return line.
Here is the electric fuel pump (mounted behind the right rear wheel) with new lines, clamps, etc ready for install). The brass piece is a line diameter reducer since the line from the tank is 1/2" i.d. but the connection of the pump is 3/8" i.d.. There was a plastic one in there originally, but I figured I would use metal. The pump is attached to a bracket which is then attached to the car. There are two rubber bushings that I replaced. The old perished ones are right next to them.
The pump has a metal cover around it when installed. I just cleaned, sanded, and painted it while it was out. This photo still has the old rubber mounts installed.
And finally I installed everything on the car. Once completed, I went around and gave every fuel clamp another snug to hopefully avoid any leaks later on.
So I was able to put the rear of the car back on the ground for now since I was finished with work in the back of the car for a while. Also, I needed the car on the ground because it looks like I will need to drain the coolant (fairly new from the previous owner's records) so I can remove the radiator.
This is a classic Italian snowball because all I wanted to do was remove the air pump and bracket....but that's not so simple. The pump itself came out fine, but the bracket that holds it proved to be a little more difficult. Once the two nuts holding the bracket are removed, you should be able to slide the bracket forward off of the two large studs sticking out of the front of the engine. But- the air pump tensioner pulley then hits the plastic fan... so the raditaor needs removal. I could get the bracket out easily by destroying it- but I want to keep everything intact for any next owner that may need to put this stuff back on.
And here is the air pump- that doesn't seem to spin very well OR push out any air- glad I'm losing it.
Here is the front fuel filter ready for install once i get my new one-way valves:
That's all for now- so far so good!

So many smells.... the sign of PROGRESS!
