Replaced both fuel filters and it ran perfect for 3 days now at highway speeds is surges and bucks.  It will idle perfect while sitting still. Fuel pump has a high pitched whine.  Were should I start?  Check fuel filters or fuel pump or both, I don't want to do either since it's 5F outside.  Thanks, Marcus

My money is on the filters.  When I had to R&R my diesel tank a couple
years ago, the filter clogged up a few days after it had been ingesting
all the debris that was dislodged when I "cleaned" the tank.  Also,
clogged filters will cause pump noise.
