I recently bought a 2016 Ford 6.7 the stock tank is only 25 gallons. So I added a 63 gallon auxiliary tank from rds. Read so much on how the cp4.2 pumps in chevy and Ford are a serious liability to these deisels. So rather then a gravity flow, as tanks condensate and deisel floats on water. I took mine a couple steps farther! I put in a low pressure pump with a filter before the pump, then goes to another filter with a water separator, then down to the tank. The extra steps was only around $60 , but way cheaper than if water gets to these pumps. From what I've read that could be a $10,000 to $15,000 repair bill. Says file to big to post, but its a nice clean easy setup.
