The stock filter’s ability to separate water is total garbage. The cp pumps burn out trying to suck fuel. Fuel pumps pump, they don’t suck is easy way to think of it. Yes I am aware of positive displacement pumps, but look up any positive displacement pump that has positive incoming pressure and you will see longer life every time.
I appreciate a stock rig- hut when there is design flaw or penny pinching that occurred for profit margin- it is a mistake to not correct a well known problem.
Get on that system asap. That is the one expensive weak link in that whole truck.
