I think there is another solution, but like archemedes said.... at what cost?
Could make an Inline one with extra radiator hose, some type of couplers and clamps to connect the hose's together. See my primitive text drawing.

My design would be pretty much disposable. But you could use old radiator hose necks off of old radiators (sawzall them?) or just plain metal pipe and hose clamps.
Just trying to stir up the creative process.
