Learned a hard lesson about fuel filters on a job near Bakersfield

I was working on a fleet of Peterbilts out by the Grapevine last summer. Truck kept dying going up the hill, customer was furious. After two hours of chasing injectors and pumps I finally swapped the primary fuel filter. It was clogged with algae even though it looked clean from the outside. The filter had only been on there 3 months too. Has anyone else had that green slime show up way faster than expected?

Yeah I used to blame the big stuff first too but this kind of thing DEFINITELY changed my mind on that.

Honestly, swap the filter first every time on those Peterbilts. I have seen algae grow in a diesel tank in like two months flat if they sit half empty in warm weather. The outside of the filter can look brand new while it is totally sludged up inside. Just start with the cheapest, easiest thing next time because the truck shows you the same symptoms whether it is injectors or a clogged filter.
