No we dont have any problems with ours as of yet anyway, but the ones on 97-98 are different as in a better pump according to decatur. The ones on the 94-96 wont push as much fuel. Just put a fuel pressure gauge on there and see what it is doing. The two pumps look the same so all i can say is that if yours will not hold 20-25 psi than it should probably be replaced. I think the 97-98 will do 30-35 psi while cruising and 20-25 under wot which obviously depends on truck mods. If it falls under 20 then i would for sure replace it. Tim
