Fuel filter change issue

I have a 2002 Safari Sahara with a ISC Cummins engine. It has two fuel filters. From left to right the first one has a plastic separator attached to it, the second one is longer with an electrical connection.

I changed them both today. The 2nd one changed out no problem. The first one, however, kept pouring out fuel during the changeover. As you can imagine this was quite messy, not to mention the lost fuel and cleanup.

My question, therefore, is how do I prevent this? Is there a shut off I was supposed to turn before I took it off?

It may have a fuel shutoff valve, but probably not.

Next time mabe try parking slightly downhill, or use your jacks .

On my Cummins, I plugged the fuel lines prior to removing the filters.

You'r experience mirrors mine. Luckily I had grabbed a bucket the first time I did it so I was able to capture all the fuel. Now I know what to expect. I'd say I captured between 1 and two quarts of fuel when I took the filter off.

Buy a extra plastic separator bowl and have the replacement filter ready to put on fast after taking the old one off.
If you are fast very little fuel will be lost.

fuel filter

I carry a spare fuel on the MH in a plastic tub with a filter wrench. I use this tub to catch the fuel if I change on the road or at home. Just learn to be fast which installing the new filter!! There is no fuel shut off on mine.
