Re: Truck loses power and stalls going up hills
Well, it sounds to me like you're getting some air intrusion. It could also be that the mechanical lift pump is starting to fail. Have you purged the schrader valve on the filter head to see if you've got air in the fuel? If not, do that and see. My truck did something simillar and it turned out to be the lift pump. I'm not quite sure how the hills would be affecting it though
Oh well, hope this helps.
