Brian, I had filled up on 2/25/15 in Lake park, Ga. and had filled up at Flying J couple of times North coming from Mo. I also never had a problem before at FJ. I did drain some fuel out of the 1st filter to ck for water and found none. When you changed out your filter did you have problems with the engine performance, not getting up to speed?

jleamont, What year and engine did you replace your fuel pump on? As I stated earlier I have a 2005 Cummins 300hp ISB.

Thanks for all the info from everyone. Rich the engine is a ISB, not the 02, I checked with Freightliner. I also called Flying J about the bad fuel and their reply was as I expected: No reports from that area of fuel problems. My next question would be how would one follow up on this? I''m sure it happens often.

Thanks for the reply Brett. I did check with freightliner and it does have 2 filters. I did open up 2 of the filters and found one had a small amount of black around the top of the filter and the other one had a white looking substance , not a lot, in between the folds, no slime, dirt or water noticable. I have used biobor in the past but not much so I think I'll have to use it more often as recommended since I had this problem. I have never changed out the secondary filter so that will get done asap. I did take it out today and traveled about 50mi to see of would drive normal which it did, buttttttt when it sat overnight before it would drive ok for a couple of hrs. and start loosing pwr., so maybe I have it worked out of the system.

Hello everyone, I'm a newbie on this site. We have a 2005 Coachman motorhome with a 300hp Cummins with a XC Freightliner chassis. Has only 25,000 mi. on it. It sits a lot in a shed but the tank is always full and treated. We were recently on a trip to Florida and had filled up at the Flying J's on the way down. Our last stop was in lower Georgia. After we drove a short distance the engine started losing power under load and missing, we were able to make it to our destination. I thought maybe the fuel filter had gotten plugged up so the next morning I purchased a NAPA filter and the counter person indicated that I might have gotten bad fuel with algae and that maybe I should add some biocide, which I did. Started the engine reved it up and idled fine thought everything was good to go. Stayed at that location for a few days. We left to go to another place 45 mi away and it ran good. Stayed there for a few weeks and started home one afternoon drove for about 2 hrs and the engine started loosing power again on hills-- I could not get over 40mph. I had purchased a couple filters and some Lucas fuel injector cleaner prior to carry along, good thing I did. Also I purchased some Howe's treatment and gave it a good dose. Changed the filter and it did OK for another 2hrs and the same problem. Changed another filter and parked for the night and filled the tank. Seems like when it would sit for a while or overnight it would do OK for awhile. Next morning it did OK but would hiccup occasionally on the steep inclines. We made it home OK and I was looking for the secondary filter which I found over the rear axle. It has copper lines attached, so I am going to change it out. I had read another post if the fuel lines are taken apart the fuel will drain back into the tank creating air into the line. It looks like it is higher than the fuel tank. How would I prevent this from happening, should I try to plug it with something and I don't think I can prefill the filter since it lays horizontally on the frame. Thanks for help, Larry
