Has anyone ever had algae in their fuel system? I was told that is why I loose fuel pressure at WOT. The mechanic showed me what looked like black sludge on my screen. He used some stuff made by Power Service to shock it and kill it, but said I might have to replace fuel lines. Just wondered if anyone has had this problem and what all you had to change.

Depending on when the FPR screen was cleaned last, its completely normal for there to be black sludge accumilated on the screen.
I'd say monitor the situation, and clean it regularly along with checking/replacing the fuel filter as necessary before throwing any parts at the truck.
Glovemeister did a great writeup on cleaning the FPR screen here:

If you do have an algae problem it might be necessary to purge/replace the fuel lines, but if it's just the result of not having been cleaned in a few years you should be fine once the debris is removed.

Im not 100% sure but if you got algae in your fuel it probably cam from where ever you fuel up at we had it in our tank at work several years back and it didnt effect any of our equipment,maybe we caught it in time but I think I remember someone saying that the algae wouldnt live in the tanks of the equip. for some reason. ggod luck with that though

FPR being gunked up is normal, but not good. Truck will run much better w/ fpr cleaned.
