Got a couple suggestions for the Hardi pump:

I'm tempted, but it appears the input and output ports are canted to
each other, I'm not sure I could twist my copper fuel lines to fit them
(the SU pumps have parallel ports). I don't see how the bolt up to the
existing bracket, either. Anybody fitted one to a BJ8 with stock
plumbing? Photos?
