I've got a 93 6.9L IDI. It sat for 4 months and cranked it up. Changed the fuel filter, then drove it 25 miles. On the return trip of 25 miles, the Fuel Filter light was on all the time from idle to 1800 RPMs. Obviously the filter COULD be clogged and needs to be replace. If I replace it, first I am going to siphon the filter out, and replace it with new. I'm wondering if there could be some error causing the light to come on when it shouldn't. I removed the two leads that connect to the filter and put them back on. There isn't a short. Any ideas?
