RAM Cummins fuel filter change interval

I think between fuel filter changes, your also suppose to drain the water separator every/every other fuel fillup. A few ounces drained into a clear container to verify clean fuel or water collected removed as basic preventative maintance as well. This is done before you get a unwanted water in fuel light indicator/message. (may not prevent catastrophic amounts of water in bad fuel though) Takes less than 5 mins. Be sure to dispose this waste fuel properly.

I had water once in my 98. The WIF light came on so I drained it and had a tiny amount of water. So the sensor worked. Before that I would drain a small about occasionally but never found a drop. So I never drain mine anymore just to look since the sensor works so well.
