    Hi,
    On my 97 3406e under the priming pump is a canister labled do not remove it is about 1.5" tall I have been told for years now replace it with an actual screw on filter.

    Anyone have a part number that fits there? Parts counter man not sure if it is same as ones that come with filter from factory. Any issue running it in series with the factory Davco 380?

    thanks,,,

    I should be the basic Cat secondaty filter, I don't know the Cat # off the top of my head, but all of ours use a Fleetguard FF5319, which they should be able to cross.

    Then look at your Davco. If all you run now is a Davco, you probably have 2 micron element in there, you want a higher micron filter in the Davco if you'll be using a secondary. We don't have Davco's, so I can't help you with part #s, but all of our Cats run a 10 micron primary with a 2 micron secondary.

    That is a 15 micron primary filter, you shouldn't run that as your only filter. That is a good filter to run once you get the secondary installed.

    I use CAT or Donaldson. Whichever I can get the best price on by the case. I guess it doesn't matter but those are the only ones I use.

    The Davco is the best system you can get buy the 2 micron filter, or even the 7.
