Item was just I needed to fix the problem.
TCM 626536 Diaphragm-Fuel Man Vlv
I had no idea replacing this would have such an effect. Old one was hard and not flexing resulting in hard starting, dying after start, rough running at idle, etc. wish i knew that years ago
TCM 626536 Diaphragm-Fuel Man Vlv
It appears just what I need. have yet to receive the parts. My Diaphragm was cracked and leaking fuel out the vent on the top cover. The rubber had de-bonded and blocked the screen for the injector port to get fuel, Was fouling spark plugs due to cylinders not firing at low fuel pressure to the injectors. IO470V
