How To Turn Up A Diesel Injection Pump. 1- remove the injector from your engine. The Manual for these engines and timing the injection pumps is a little vague.
I know the 62 isnt a monster its not supposed to be but i want to try turning the injector pump to get a little more power and smoke wouldnt be. Oh yea and dont forget to remove the fuel inlet line thats the one in the middle of the rear of the injection pump. Tue Dec 11 2012 613 pm Post subject.
2- hook the steel fuel line back up the the injector with the injector facing away from the engine.
For additional power with the VE larger injectors can be installed. To do that on a inline multiplunger pump as used on the M4950 you adjust increase the rack travel. Tue Dec 11 2012 613 pm Post subject. Your best bet to turn down the fuel is to back the screw out 116 turn.
