It runs and drives,with elect fuel pump off,but smokey.
The car smoked sence I bought it(a year ago)- but not as bad
The smoke was slowly getting worse -over time.
So I'm not to concearned about when the elect pump dies-as the car is drivable either way.
This is what I'm thinking:
If the elect pump last 1 year then dies- I'll drop the fuel tank & try deleting the elect pump.
If the elect pump last 10 years- then I'll probably put a new elect pump back in.

 Do you have a clear fuel line going from the I-pump to the tank? Any air?

 Air in the fuel usually means a fuel line restriction is causing a vacuum that is expanding disolved air in the fuel.

 Not understanding why it would flow more fuel while turning by hand without the accel lever pulled than it would with?

Starting is pretty much a max fuel scenario as the pump tries to compensate for 100 RPM idle regardless of throttle position.
