Thank you for all of the wise words of advice. I may start with bypassing the fuel tank with a temporary one. Hopefully I can narrow down which end of the car the problems originates from.

I am guessing that by loosening the fuel cap and if that solves the problem, that would lead me to the tank vent? Where would the vent be located?

I noticed when I use the manual push prime, it gets tighter but not really tight like it used to in the past. I also had to help a friend out with their 240D that ran out of fuel. That push primer got really tight like mine used to. It is the black topped prime assembly.

The comment on me tightening the ALDA. The screw on top was wobbly loose. I just tightened the lock nut underneath the screw, so it's not able to move at will.

I will report back with my diagnosis. I hate it when I find a thread on my same problems and no one ever post their solutions!!

Thanks again!
