Hi all, I have had fuel contamination issues on my 1995 Ford 8340. The tractor started lacking power and wouldn't rev flat out, so I cleaned lots of gunge from the sediment bowl, changed the spin on filter, blew the primer pump out (it was clean), cleaned the brass elbow tap and blew back to tank. I bled her up, it revs flat out now but she still lacked power when under acceleration. I have checked all fuel pipe connections are tight and it doesn't give any symptoms of drawing in air such as poor starting or erratic revving.
I removed the cap on the end of the injection pump to clean the inlet gauze filter out but it doesn't look like pumps I have seen before on 4000's!
Has anyone got a better diagram or a photo than the NH parts diagram (attached) which doesn't look correct. My cap (70) has a female groove which drives onto the top of (66) - much like a screwdriver and slot. I didn't go any further with removing the filter, so I screwed (70) back in, reassembled and tried to bleed her but she doesn't seem to have enough fuel at the injectors now.
I was very careful not to disturb any of the pressure regulating valve when I removed the cap but I think something must be wrong now, any ideas?
