Dodge

I have a 2002 dodge cummins with 80000 miles and i have the edge with attiuide chip 150 hp bd injectores a southbend clutch a new vp44 pump and a fass 150 gph fule pump my problem iis when i floor the truck it goes but as soon as i let off it sputters realy bad and sumtimes dies i changed the filters and the shop says the truck is suckin in air i have to wait two weeks till the guy who installed my pump get back in town but dose someone have any ideas what could be causing my air problem

Check the fuel heater element down by the fuel transfer pump ive found these melted and sucking air if this is the case it can be bypassed
