put out 750 in the shop yesterday, thought needed a new fuel filter. we changed the one under the hood ourselves but couldn't get the inline one done (the one under the hood took 1.5hrs) took it to the shop asked them to do it... turns out the lifter pump is kaputt. of course just went out of warranty, 56k miles and the part is $450 with about 3.5hrs of labor! So we're pretty much talking $1k. Talk about being bummed out, main reason I bought this truck was for "longevity."
