Omar, Jim,
The 2 small checkvalves don't fit any which way on the smaller pumps.
The fittings coming off the hardline is the same as for the 3
big pumps. So.....5 total big ones would have worked fine, but
the small ones don't have manifolds on the pump that are split
flange. They are screw-in style - so the checkvalves cannot be
mounted on the pump end, only on the hardline end. To fit on the
pump end, we have to get from 1.25" NPT to -20 tube, flared fitting, etc.
 These fittings are
not going to work well no matter what we do; it will be a kluge.
We can probably do a NPT to tube w/ 2 more hoses and make it work.
Unfortunately, the print is not clear on the NPT size so we cannot
just call Seoul and get some fittings.

Please advise what you want us to do.
Rod
