Water/Fuel separator question?
After empting the separator filter by the drain valve how do we get fuel back in the filter to start engine? Cat 2004 c7.

FYI there is not really a need to drain the fuel filter unless you like major tow or service bills. This is something sales people who don't know what they are talking about tell newbie diesel owners. If you feel the need to check for water, just drain a small amount into a container, if you have a water issue you will see it in the bottom. water and diesel will not mix and water is heavier than diesel so pools in the bottom of container. I drove commercial truck for over 40 years and went 10 to 12k miles between services and never drained fuel filters. Could tell when a problem, would remove and dump out filter to check, refill and replace. Over 2.5 million miles and only changed filter on the road 3 or 4 times. We always carried a jug of fuel and refilled filter before spinning it on. Just my experience.
