.....I might be being pedantic here but the hose routing is not the same. In the 14 and 20 the HP hose will rout above the inflator hose and on the 21, SE, SE2, SE3 and 22 you can have the HP hose under the inflator hose (a little neater). Yes, the meat of the 1st stage is identical in all these models the only variation is the finish, number, size and spacing of the ports.
Yeah, to me that is close enough to call it the same. Whatever floats your boat though, or sinks your submarine. Plus, you had excellent word usage.
