Cummins ISL hiccup
Ours is an 03 Cummins ISL with 20K miles. Just serviced with new filters before a trip form Fla to Utah. It ran perfectly until the 4th day when it started to develop a very brief sudden loss of pow...

sofar-sogood.....If you're comfortable with it, the filters should just spinoff with your hand if they were recently installed. If not, you can wrap an old leather belt around the filter, pinch the belt as tight as you can with pliers or vise-grip and lean the pliers in the direction you need to turn.
Both filters have a large rubber o-ring, just a little larger than the o-ring you find in the end of a garden hose. Two things may have occurred, either one of them was left off, or there are two on one filter. Remove the filter and check the end of the filter and up into the filter housing.
If the O-rings are in place, pour the fuel out into a bowl and check for excess water or other visible contaminants. If the filter is clean, refill it with clean diesel fuel (buy small gas can). Put your thumb into the center hole, blocking it off and pour the clean diesel into the filter around the outer edges.
The ISL is suppose to be able to start with empty filters by turning on the ignition several times for 10-20 seconds to fill the filters, but I've found this to not work well.
