I still have 2 fuel injectors that are failing flow tests. Today I used my air compressor to blow them out. The two problematic injectors look to have some rust/oil/crud build-up inside them. I decided to soak them in the bath for a few more days as one last resort. If they still don't work at that point, I'll replace them.
I also inspected the fuel tank area where the pump and sender unit reside. There was a decent raw gasoline smell in this area so something isn't sealed-up properly. I'm going to rig-up a long fuel line and a bucket and jump the RPM relay to empty the gas tank of the old gasoline. I'm also going to replace the rubber fuel line sections and see if I can locate the source of the smell and fix that.
The sender unit says "delorean.com" so this has been replaced at least once since new.
A previous owner at some point installed a speaker in the storage compartment behind the driver seat. I took out the custom fabrication and put the factory door back on there. Looks much better!
