Calling all diesel guys!

Depends. I really think they just grabbed what they had lol. I’ve worked in an 09 6.7 liter with a lift pump on the block.
Learn something new everyday. I just went out to check and see if the pump was for sure in the tank and for the heck of it bumped it over and the dang pump started running. First time in months that I've heard it, but I still think it's on it's last leg at 265k.
