I have a 2005 Dodge 3500 (5.9) that feels like its not getting enough fuel out the hole but no problems at med to high speeds. I thought it was the pick up pump in the tank and installed a Flowdog 150 and by-passed the fuel filter container next to the engine. I still have the the same problem. I have a Bullydog PMT on the truck and its not giving me any codes... HELP !!!!!
