Check which system you have before buying a part
The pumps are model-specific: 97605 belongs to the portable Turbo 300, while 97611 belongs to the permanent Turbo 400S. The 300's 15-foot hose with clamp (97630) is not the same service assembly as the 400S 21-foot hose/nozzle/coupler kit (97521). Thetford lists nozzle 97520 and cap-and-gasket kit 97514 for both models, but their connections still need to match the existing installation.
