D4 7j fuel/governor problem

On a recent D2 post Hector "Gemdozer" gives the part numbers for the D4 Fuel Filters and Gaskets.
Have you changed yours yet?

Try to get some diesel fuel conditioner/cleaner into your system, maybe a 50-50 mix thru the transfer pump. I have been using an Agco product with good luck, comes in quart cans. I had a set of pumps from a 13000, all stuck. pulled them off and soaked them in pure conditioner and they worked like new.

Hi Indian4cyl,
as your pump is intermittently sticking dick has a good sugestion with the fuel conditioner.
If this doesnot help then you could have a broken lifter spring.
If you can remove the side cover from the injection pump you should be able to gently lift the offending lifter with a screw driver or similar lever and test the spring tension as compared to any other lifter.
if it feels the same you may need to remove the pump unit from the main body and try and free up the plunger in its pump barrel--if this is found to be the problem.
Be sure to re-time the line on the segment gear, on the plunger, to the line on the rack bar when re-installing the plunger and pump unit. You will most times need to install the plunger in the lifter yoke before you can then fit the pump unit--depends on the angle that the lifter yoke needed to be adjusted to, to obtain the lifter setting.
Hope this helps.
Cheers,
Eddie B.
