Hope someone can point me in the right direction on this. I had the Superdiesel lift pump and filter installed last week and now the truck has a hesitation. It happens when I get on the go pedel quickly. It has done it a few times from a standing start and is real bad while cruising down the road. If I get on it more than half throttle it wants to hesitate and then take off like at beast. I've tried with the pumps on and off. It feels like a old quadrajet carb hesitation. It acts like it's getting too much diesel poured in at one time. The Superdiesel set up is a flow through, so when they are off, it should only be running normal fuel rates. Anybody have any suggestions on where to begin the trouble shooting? Thanks!
