wrap the pump in a bicycle inner tube (2$) and slide it into the oem rubber housing then simply bolt it back in place like oem. take the rubber hose and CAREFULLY place in your closest trash can. its a vent hose thats no longer needed. if you up to the task remove the old pump housing take the oem female plug apart and solder it to the johnson electrical leads. now you have a oem plug setup with the proper resistor in place. takes all of maybe 2 hrs.
