Dometic
This maintenance kit includes everything needed to rebuild your pump (minus motor) to make it run like new. Confirm your pump type (8 bolt) by reviewing the alternate picture above. This is called an 8 bolt pump from the number of bolts that hold the lid of the pump to the pump body. If you have a big metal clamp holding the pump together you need a different kit to get the correct o'rings -Follow this link

NOTE: Please be aware of Knock-Off Bellows being sold by companies that are not affiliated with Dometic. They will not fit Dometic pumps. They are too tall, too thin and are not sealed to create or hold vacuum. Here is the comparison of the Dometic Bellows vs the Knock-Off.
Bellows Installation Tips:
STEP 1: Make sure the o-ring is INSIDE the top lip of the bellows!!
STEP 2: Snap the bellows into place by squeezing the bellows and the pump top together.
STEP 3: The o-ring should not be visible from the side view. It will be sealing the bellows opening to the pump top inside the bellows lip itself.
STEP 4: Clamp the bellows onto the lid. The flat side of the clamps should be up, against the lid.
