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?
