oops!!!!!

Go over to boatdiesel.
go to index.... = CAT C7

read through some posts. mostly people asking the same question as you and people looking for solutions to problems.

btw, what I mean by "....people asking the same question as you and people looking for solutions to problems " on boatdiesel has nothing to do with CAT products in particular.

boatdiesel is a good place to read about problems and find solutions on any make marine diesel.

Join Boatdiesel and learn to use the search function. Lots of issues out here ( SF) in the 7 and 9's with fuel pumps and injectors. Cat guys changed out complete set of both in two charter boats with twin C-9 two weeks ago on my dock. 7 ltr sounds lite for a 37, but tYour local support is as important as the size and color of the engine.
