don't hate the vp44 it is actually a very good pump john deere has used this system for years on tractors with no issues. The problem with them is poor supply fuel to them, in fact to the death of the vp's is because they are a good enough pump to pull fuel through the dead lift pump and still run the truck, the reason they die is because once the lift pump dies they cannot pull more fuel then it needs and no xtra fuel( lift pumps job) overheats the pump and kills them.
