Hi there, I have a 66' c-10 with a 250 inline six cylinder motor. At one time, I had the truck running but one day it decided to quit and only run if I poured gasoline into the intake manually. I checked the fuel pump and it worked fine. so i decided to rebuild the carb. after checking all my passages if they are free or not, the thing still will not run for lack of fuel. Note: I understand that you have to soak the plunger in oil for the accel. pump to work, (I soaked mine in WD-40) yet it is still not pumping properly. Have i used the wrong soaking procedure, or is there another problem i should check?
