It's the 4.3 that has issues cuz it only has two Pistons the 3.2 has three Pistons remember the 4.3 has two Pistons but has rollers at the bottoms of the cups and if they are not running ultra low sulfur diesel they will have issues and it will basically not have enough or the molecules ain't small enough for lubrication of the rollers on the high pressure pumps. 4.3 cups have rollers and the 3.2 has no rollers it's a flat faced cup so the cup can spin all day long and never have an issue with the roller going sideways cuz it doesn't have rollers the 4.3 has cups and rollers at the bottom the issue with that is they never put a keyway on a cup to keep the cup from spinning

I saw this in real life, it basically self destructs you can see the scratches from where the metal makes contact with the housing it rides in.

Not sure where you get non ultra low sulfur as that's all I see but maybe that's one possibility of what causes issues, not a tech but tech sent me this

Hmmm bet that other color of diesel isn't low or ultra low sulfur.

Off road diesel that is dyed red is the same stuff as road diesel. The only difference is the color and the road tax.
