Installation Notes: The original cast hose fitting is replaced by a 1/2 inch NPT port. Older models require a 1/2 inch NPT x 1 inch hose fitting (P/N 50-512-017, sold separately). Newer models use a 90-degree hose fitting (P/N 3852538, sold separately). It is recommended to replace manifolds in pairs and to replace risers and elbows at the same time for optimal performance.
