Description
This Busch part is made from material that can handle pump oil and operating temperatures. Never reuse the old gasket after you remove the cover. It gets flattened and won’t seal well again.
Installing this new gasket is a simple final step. It guarantees your pump is sealed up tight and ready for reliable operation.
A good seal here is important for two reasons. First, it prevents oil from seeping out and making a mess. Second, it stops outside air from leaking into the pump. Air leaks force your pump to work harder and reduce its vacuum power.
