Hey everyone just got my first Cummins and love it but the I keep hearing about turning up the fuel screw and bumping up the timing on the pump an 1/8 turn. Does anyone have any pics of these thing because I don't know exactly what needs turn and if its clock-wise or not? Any and all advice will be awesome. thanks all

 

Go to youtube and check out some vids on there. A guy has some vids on the gov spring, pump timing and tuning. But yes it is clockwise for the timing advance if you are looking from the back of the pump.

 

First off..



Then read this thread and look at the links.

And remember more fuel only = more heat if don't have the air to burn it efficiently. Any more than modest fuel increase should be accompanied by supporting mods: intake, exhaust and turbo upgrades or you risk bad things happening from excessive combustion temps.

If you haven't already, get EGT and boost gauges installed, as a minimum.

 

thanks for the input guys it appreciated
