    Hello Fred,

    The Walbro pump has an easily replaceable (and cleanable) screen filter. It
    takes about ten minutes to do.

    To quickly and easily clean a Walbro 68xx pump:

    Take off the metal band mount band. (1 Nut)
    Pop off the brass end caps with a flat blade screw driver
    The plastic housing falls open like a clam shell
    Undo the three screws holding the base triangular plate on.
    Pry open the base plate with a flat blade screw driver
    The screen filter will fall out into your hand.
    Clean out the base chamber. The screen can be gently cleaned or replaced for
    about $2.50
    (Yes Walbro sells a replacement screen for this "unserviceable" filter.)
    Carefully reassemble. Make sure no grit is caught in the o-ring.
    Check for leaks.

    Time: about ten minutes.
    Money saved: $150

    Let me know if you need help. I'll e-mail you pictures and directions on how
    to do it.

    Thank you,

    Charles Bell
