So now Donkey isn't using all 4 cylinders. Old B engine of course. (1 Viewer)

Once the filters get here, I need to figure out how to purge air out. I don't see a purge nut seen in a video posted here on my pump. If I still have the hesitation after changing the filter, can the injectors be cleaned? As I can't seem to find any rebuild or good used ones out there (12V) that seems to be the only option. I've done the simple thing of pouring a can of Seafoam into the tank. Problem didn't exist at all until I filled at a Shell station at last fill up.
HELP

What symptoms are you seeing exactly? If this happened after you changed the filter I'd start there, I am assuming you have a cartridge style filter (not simple spin on) with that engine and that their may be O-Rings involved? Its likely you're sucking air if its running rough and if you DEFINITELY put diesel in at that last fill up.

Haven't changed filter yet. It had been running pretty well. The o lyrics event that proceeded the hesitation was the fill up. Feel like a misfire in a petrol motor.
