The ticking time bomb under the hood

Two of my friends had the Bosch CP4 high pressure fuel pump grenade in their 2012 F350s with the 6.7 liter Diesel. It took out the entire fuel system and injectors.

Both trucks had over 130,000 miles on them. One got Ford to pay for part of the repair the other didn't. One was out $7000 and the other $16,000. I had 118,000 miles on mine so I opted to not wait and had mine replaced for $2700 parts a labor plus tax. Apparently the Bosch pump needs more lubricity than US ULSD provides. Oh and the other diesel engine s use the same pump. Do a Google search, there are even class action lawsuits in the works.

Anyways back on point. The repair only takes a day, one dealer local to me wanted to take 5 days at twice the labor charge while one 30 miles away did in in one day for half the price so shop around.

Here is my parts invoice as a heads up
