I like your idea for the return line to the filler neck.  This car has been sitting since before Obama was in high school so the tank will be removed for cleaning anyway.

I learned about harness grounds on the Spirit with the feedback carburetor. The ECM system for that car is a dead ringer for the throttle body system which came out at about the same time.  If you remember I had problems getting the ECM brain to work properly and I even bought a re-manned box from NAPA.  You helped me with the damaged PROM chip for that box. It turned out that the system was not grounded properly (requires a ground wire to a forward head bolt).  I wasted a lot of money, but I did get the system up and running and I learned a lot about open-loop/closed loop operatons.

I expect I'll need nelp with the tuning when the time comes.
