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.
I have another question for you pertaining to this '05 truck. The CP3 pump has a weep between the two halves at colder temps. I have read that the bolts can back out and just need to be retorqued. Do you think the seals are actually bad or could it be those little torxs head bolts can back off?
