Hey to ya`s, I`m just wandering if anyone has figured out a good idea for a small pump motor that would fit inside the housing of the windshield washer motor housing. The setup in question is for the square fluid container with part number 671723 on the side of it. It has the plastic motor housing on the fill lid with a red or black plastic cap on top. I have seen them on 544`s 122`s and 140`s. It would be nice to fit a small pump in that housing with a hose down into the washer fluid and still have the original look on the outside with an exit hose to the washer nozzles coming out of the bottom of the motor housing. The reason for this is I would like a spare for the 544 as I have an extra setup with a bad pump and another with missing parts. Thanks! Larry
