hey all. i dont usually have any question on working on these engines, but today im a little puzzled. i changed the stock lift pump on my 2001 with a raptor 100. i had this lift pump on my other 2001, but i just got that one an air dog 150.  anyhow, ive changed lift pumps/filters on these trucks 20+ times and have done the bleeding procedure as anyone would. crack lines 1,3,4 bump a couple times till you get some fuel, crank until air is gone and fuel is clear, close lines, start. toda
