Glen Gonyea Posted January 22, 2016 Share Posted January 22, 2016 Have a 1993 CH 613 E7 400... Boss wants to switch to a mechanical fuel system..anyone willing to share any expirence of decent success with this. The problem with the truck now is it runs but has no power..when I hook the MODIS to it its like the software is blank and has computer issues... I think it needs a new VMAC module.

alex g Posted January 22, 2016 Share Posted January 22, 2016 I've heard success stories from this but I believe you'll have to bring pump in to a specialist and they change back of pump and I think it also changes timing but that's beyond me.
