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..

Fuel filters usually fit several different bases. Ours at work had three different types of seals in the box. Whatever was working, use the same thing. Some of the bases had grooves where the seal went. You had to dig the old seal out to replace it. Some guys didn't and ended up with two seals in the groove and it sucked air.

Hmmm, my last MH had a Cummins and the fuel filter used a flat O-ring on the threaded stub where it screwed on. Is that the O-ring you are talking about?

+1. Both of my primary and secondary filters require the small O-rings. Cummins ISL.
You sure the one from the previous filter did'nt stay on the mount, and you ended up with two ?
