Lesson I learned on fuel filter change..
On my MH's ,maiden voyage I learned my fuel gauge doesnt work right.. Luckily I ran out of fuel from my trip in my dive way.. I have never had such good bad luck..lol.. Anyway.. after figuring out my problem I got it back running and decided to replace the fuel filter.. carried my old one in and got a new one.. when I was putting it on I noticed it had a extra o-ring with it.. my original one didnt have one.. I figured it was new and improved and put it on with the o-ring.. fired it up.. drove it about 10 miles and only had it miss a little once or twice.. I figured it was clearing out some trapped air.. few days later loaded the wife and kids up and took off.. about 5 miles from home, I was about to pull onto the interstate and I hammered it down and she shut off..I coasted into the parking lot of a motel.. after 30 minutes of breaking the injector lines loose, bleeding.. having it start and then quit I gave up and call my buddy to come get us.. the mechanic didnt show like promised the next day and the motel owners were having a fit, at midnight I carried a air compressor up there built up the air, and got the brakes off and pulled it with a chain into the back lot.. the next day I got another filter and replaced it..this time with out the o ring... she started right up and I drove her home.. The guy I took to help me fix it, told me that if you have a Cat motor, use the o ring.. Cummins... no o-ring..
