Cummins ISB275 fuel/water seperator
I know this is an old subject but I just changed this filter. I filled it about 1/3 w fuel only because I ran out; put it on the mount and turned the key 3 times to prime. The engine then started, ran about 30 seconds and died.I am aware of the air in the fuel line problems so I loosen the 5/8 screw on the bottom of the filter and could see a lot of air bubbles. When this stopped I again tried to start the engine but no go!
Any suggestions at this point would be greatly appreciated.
