I'm 90% certain the both of us are experiencing the same issue.
The stock xfer pump failed again, so it will be replaced by an Amazon.com special and some rubber isolator mounts. I have looked into gerotor / Carter rotary pumps but will need to do some measuring tomorrow (I doubt it will fit in the stock location).
Even when the xfer pump was working, and the gas tank was confirmed to be free of the weird pink slime on the pickup tube sock, and new filter installed (old filter was full of pink slime), the car still doesn't want to run at cruising speed and the AFR will drop lean then off the meter. Only comes back after a blip of the throttle. Very frustrating, but I'm starting at the tank and working my way towards the injectors.
Protip: Don't let your car sit for extended periods.
I'll try to post a vid (or link to a vid) of the AFR gauge during a steady cruise down the road and a link to an old vid I have of the car doing the same thing, but on the highway at a constant speed.
Cheers,
Terry
