after 6 months of sleep I charged the battery and took the 73 for a ride it rode fine plenty of pep put a smile on my face. As I was leaving the grocery store at the light the car choked and cut off. Some young guys helped me pushed the car back off the street into a parking spot. By coincidence a car meetup was going on around me. The young guys were excited for me to open the hood of this 2002 or whatever it is. Now come class time I opened the hood and pulled off the air filter with just two nuts and viola two carbs. They all leaned in as I showed the car's simplicity. We took a hose a loose and I cranked no fuel came out. I showed were the fuel pump was and took the output side hose a loose and cranked the car again no gas.. My daughter picked me up and took me home and I took the fuel pump off of my 71 with a 3.3. I put it on my 73 at the parking lot and after some cranking the car started and ran well. By the way the bad fuel pump was only 2 years old.
 
Stock mechanical pump?

I changed to a Pierburg electrical pump, and I carry a spare fuel pump with me. I also installed the pump where I can access it laying on the ground and installed a set of pigtails so the electrical part of it is easy.
 
I ran a completely separate wiring circuit, but I had installed a distribution block under the rear seat for my Schrott Harness inertial reels. I also installed a Revolution Electronics fuel pump controller, which is wired like a relay (with a safety circuit that shuts off the pump if the engine is not running).

Here is a description of my setup:


My pump is mounted on the right side, near the area where the tension strut attaches to the rear subframe using one of the bolts for the subframe mount. I had an area of crushed fuel line I removed there, and I was able to tuck the pump up where it is relatively well protected. If you look in the thread I reference, you can also see Macha's mounting location, which is in the trunk. I wanted to go lower to avoid vapor lock, but I don't think Chris has had any problems with his setup, and its easier to do than mine.

One last thing - yes I did install a block off plate. There is a BMW part for this. Don't recall where I got it.
 
i see Pierburg makes a couple of models any particular one? thanks
