6.0 injectors keep blowing, any ideas on why????

[Bigens350]

Hi, I have a 2005 f-350 with 135,000 miles. I recently had my high pressure oil pump go along with my #1 injector(In August). As of today my my #3 and #6 injectors are also gone. I would like your guys help on find the reason why these keep going. I run fleet farm diesel as much as I can. Any thoughts would be great.

Low or negative fuel pressure.

In my experience when 1 injector goes out most of the others are close behind since theoretically whatever contaminants got the first injector 9 times out of 10 made it to the others. Water will destroy these injectors and so will low/negative fuel pressure.

Dont know about down there, in Canada it's the same ****, just with dye in it because there's no road tax on it.


It's even ULSD.

Ya but it usually comes out of an old sh*tty farm tank with water/rust/dirt in it.

Well down here off-road diesel has a higher sulphur content llower octane rateing and more parrafins and varnishes. Really messes with these new unitised injection systems.

I used to haul gas on weekends and at the tank farm i filled the on and offroad fuel. the only difference between the two is the dye that i added before filling the off-road compartment. its just a road tax thing.
