Counting the original, my '99 Winny now has its fifth fuel pump. I probably should note that one replacement pump failed pretty much straight out of the box ... so it may be better to say that my Winny has used three fuel pumps to get me 350k miles .... or roughly 115k miles per fuel pump.

My first replacements were all full sender-pump units made by Airtex from AutoZone. I could have just replaced the fuel pump motor unit with new screen ... but I find it easier to replace the entire unit.

This time, this fifth pump, I discovered that Bosch also made a replacement pump. Always respecting this brand, I decided to give Bosch from Advanced Auto a try this time around. I dropped the tank and removed the failed unit before even opening the box and getting my surprise: The Bosch replacement unit did not include a pressure sensor! So, they intended for me to move the sensor from the failed unit to the new Bosch unit. Not a big deal to remove the sensor from the pump unit ... if it was still installed in the tank. But this becomes a very tedious task once the pump sender unit has been removed from tank.

Tip: Be sure to inspect new pump sender unit before removing the old unit from tank! Then you won't have to wrestle the thing across the floor as I did.
