Procedure Fuel Filter Replacement (6.4)
#16

I always open the upper filter first before draining the separator. I believe this allows fuel to drain properly and not continue to flow down as air is allowed up from an open HFCM. At any rate in a dozen or so fuel filter changes I've never had more than about a quart of collected fuel.

I changed fuel filters on 2010 F350. The fuel never did stop running when I removed the frame filter. I changed the engine filter 1st. The filters are in but can't keep the engine running for more than a few seconds. Then I have to go through the turn key on for 30 seconds six times just to get it to run for a few seconds again. Anybody have any ideas?

Still have air in the system or the fuel cutoff switch tripped.
Do this: Turn the key to the on position only. Leave it there till you no longer hear the low pressure pump running.
turn key off and repeat.
Ignore the 30 seconds the book says.
Also check your fuel cutoff switch to see if it tripped. It is located on the passenger side of the dash.
Open the passenger door and right on the side of the dash is the door.

I turned the key on and off while listening to the fuel pump instead of timing it. I checked the fuel cut-off switch. It didn't seem to be tripped, but I depressed the red button anyway. I started it but it only ran a few seconds and I did the key thing again and it started for only a few seconds again. I have taken about 4-5 gallons out of the drain valve on the frame filter. Probably at least a couple of gallons went on the ground. Could this be why there's so much air?
