Hey MissSilky,
There are actually 2 popular options for pump replacement. The Johnson CM30P7-1 that Rob @ Needswings sells is the more heavy duty type pump. It requires rewiring the connector and would cost more for the install. I just replaced mine with the other popular model, the Bosch 0392022010, which is an updated version of the OEM pump. It's a simple plug and play install. Bought mine online here:
Mercedes Auxiliary Water Pump - Bosch (OEM) 0392022010 | FCP Euro
Welcome to the Permagrin crowd and get yourself a FuzzBuster. I know you'll need it here in FLA. Mine has saved me almost daily and has paid for itself 100 times over !
