Great idea, I will see how they feel with a wrench tomorrow. Interestingly, the fuel pumps do not shut off with the key on and the engine not running. When I did the fuel pressure tests, I had the metering plate sensor unplugged so the pumps would run.
After plugging it in, the pumps continued to run. I wonder if I have some resistance in the metering arm or the distributor piston near the bottom of the travel.
