Remember the Toilet Paper auto filter add on as did not have filters on older engines!!
Heck most way back had dipper rods and no rear main seal-reverse screw.

My recommendation has always been to use factory parts while a machine is under warranty to avoid the excuses to not cover a claim.
Like the old Luberfiner Filters, just a chance bypass catch hole.
Forgot to add, AFTER I left that shop they got a NEW Toy, Trash service Required ALL Filters be Crushed prior to dumping in trash. Used to allow to sit on a grated drain pan 12-24 hours(Some times a week!) but that changed, a New Kid dumping drain pains put a 750C in the crusher, according to the guys I worked with, the explosive force Dented the Protector shield around the filter and almost filled a Five Gallon bucket of filter media once Decompressed!!!
Gulf Coast filters sells large water separator fuel filters, mostly marine, I think, that can use a whole roll of Bounty paper towels as a filter element. They sell the elements, but they say the towels are an acceptable substitute in all their documentation. These filters are expensive, but have a great reputation in the tug boat world. I have one as the first step in my fuel polisher, and it works great.

LF777 was the bypass on every 2 filter Cummins I've ever seen.Can remember the first Two Filter head spin on system Cummins sent out with a Bypass Filter, even numbered after the old Can Style, LF750. For FOREVER LF670 main spin on.
