I was told by an old time A&P that Cessna had a belt driven vacuum pump on early models after they pulled the venturi off probably around in the 60's. It might be an option for KR Builders with Vairs if it were true.
1) Does anyone know what models and years that they had belt driven vacuum pumps? 2) If replacements are still available? Thanks, John Monday KR2S Laguna Beach, CA
