About this item
Alright, diesel guys, listen up!
If you're working on a Cummins 4B, 6B, B5.9, or 8.3C engine, this BLK PRO fuel supply line tube is what you need.
It's a brand new part, direct replacement for those old crusty lines with numbers like 3937342, 3926263, and 3918772.
This is a super common line that fits a ton of applications—think Dodge Ram, Peterbilt, Ford, Freightliner, and even marine or genset uses.
