Welcome. The Wayne 80 and MS 80 are the same pumps. Wayne bought out Martin & Schwartz in the 50's and just rebranded the pump Wayne. Parts are interchangeable. If you want your computer rebuilt to perfection, do yourself a favor and ship it to Joe Yocom. He does a fine job and is a good guy as well. Good luck, Paul www.severngaspumps.com
