The kit sells for around $400.00 and a reputable shop can install it for $600-$800. My buddy just had his 6.7 Ford done. Glad GM/Chevy did away with that POS pump.

I completely agree. I installed mine myself about a year ago. I sleep much better knowing it's on there. Here is a video showing what's involved when they fail without the S&S kit.

CP4 to DCR pump has finally gotten CARB approval.
