Re: Looking for a GMC 401 Water Pump
we ate several of these pumps in our 1947 Flxible Clipper 29 passenger motor coach. bought a 22 inch fan with 6 injection molded blades around an aluminum hub. had a friend machine the hub to fit this air brake style pump. weve run 5,000 miles with no issues. found some more air brake style waterpump part #s : NAPA 42105, 55 5005; Airtex AW 5005; GMB 130-6005
