    Did the 2002 320DA with 5.7's come with the problem cool fuel units? Thinking of looking at one and just want to know what to look for.

    If you get an answer, I have the 2001 4.3’s. I would expect it to be the same system. As of now, I have no issues.

    My '05 340 had CF2 - no issues. The problem is with CF3 which came out in '06.

    Didn't a few years have problems with plastic fittings breaking? Not sure if it was cf2 or cf3.

    So a 2001 would be a “CF Generation 1”?

    It should be the fuel pump mounted on top of a copper cooler in a black box on lower left front of engine looking at the stern
    Unsure if its a CF1 or 2
    The 320 replaced the 310 halfway thru 02
    My 310 is a 2002 and has CF setup i described above.
    You could check mercruisers parts website using the serial numbers of the engines.

    That does describe the look and location of the fuel cooling system on both of the 4.3’s in my 01 280 DA. Hopefully it was the version before the problematic ones were installed. I have enough issues to work through right now.
