Ok I decided to turn my fuel pin and adjust the star wheel under the diaphragm. What I have read is to turn it 1 to 2 turns clockwise. Mine will only turn half a turn and bottoms out I know the pump was replaced at 65000 miles the pump was set to Colorado specs. ( that's where trucks from) should I leave it where it's at will it hurt anything if it's all the way down? The pin was on the slowest slope. Thanx for any help

 

I dont think it is all the way down........... i mean as long as no one tampered with it when the new one was put in........... those things dan go a ways......... not just a half turn.......... maybe somthing under it?
