    Davco 382

    Anyone have an idea why the level of fuel in my Davco filter would fluctuate with the amount of fuel that I have in my tanks? Have around 18000 mls on this service, fuel is about 1/4 way up the filter in Davco unit with 1/4 tank of fuel. When I fill up, level in Davco goes up to around half way up the filter. Just noticed it doing it this week, I don't think that is right. Truck does not feel like it is sucking air, any guesses?

    Doesn't look like anyone has any experience with these things. Maybe just take the thing off.

    Mine Fluctuates as well. I think you have nothing to worry about.

    I change mine every 10,000 miles.

    you have nothing to worry about. it has nothing to do with the amount of fuel you have in the tanks. when you drive to get fuel, your filter filters. when you add fuel the davco filters it. I have the same sys & some times the filter will need to be changed with service at 10,000 miles sometimes before at 8,000 miles, other times it is 3/4 full at 10,000 miles. you can park on a fri just after a week on the road & look at the level in the davco, then without starting the truck all weekend look at it mon morn & it will be a couple inches higher, than where it was fri. Always carry 2 spare filters. donaldson is about the best. oem detroit filters have to high a micron rating, cost a lot less & don't fill up to around 30,000 miles, but oem on this, is totally inferior.

    one more thing. if your at a 1/4 tank & outside temp is fluctuating a lot. 90 in the day 50 at night, you may get some condensation in the tank, just like winter weather, it is advised at keeping tanks full if possible. when you fuel from a 1/4 to full you may get some condensation mixing with the fill up, causin the davco to catch it. at least you can see what is going on, that is what I like about the davco.

    Where is your filter mounted if it is bellow the top of the fuel tank when you fill the tank the fuel will seek its own level and if bellow the tank it will be higher in the davco

    I may be wrong, but I don't see how it matters. the davco only rises as it filters. not as the height of fuel changes it's level. if the davco was mounted 3 ft higher than the tanks, it would still rise to the top as the filter clogs, & if it were 3 ft lower than the tanks, it would not rise in the davco anymore than it would otherwise. I may be incorrect, maybe I am missing something in your version.

    My filter is located towards front of the engine on the drivers side, up higher than fuel tanks. I usually run about 20,000 mls between service and have never had this filter plug up. Most of the time when I change it at time of service it has only used half of filter capacity. I do use fuel treatment to control condensation build up cause I go 2 or 3 days between fill ups. Usually use the Donaldson filter. Thanks for all the reply's, I just haven't noticed the fluctuation as much before.
