i am very familiar with 12 valves, in fact i know them in and out, know a lot about 24 valves up untill about 2002 or untill the new body style. is the lift pump as common of a problem on these 3rd gens as they are on the older 24 valves?, im interested in buyin an 06 with the 610 motor.

 

The 2003-2004.5 were worse than the 98.-2002 lift pumps. The 2005 and newer trucks use an in-tank lift pump and are extremely reliable, even up to about 450-500 hp.

 

ok thanks so ill be fine then with an 05-06
