The "ins" are a common passage and the "outs" are a common passage. Therefore, you can use either in with either out. The duplicate ports
are not for a second motor but are there to facilitate plumbing for different applications. With twin engines, you use two filter/separators,
one for each engine.

I am about to install a yamaha standard water seperating fuel filter. The
assembly portion of the filter is set up for two motors, I have a single
motor. On each side of the assembly is an "in" and "out" arrow. Can I
install my in and out hoses on one side of the assembly, or should the in go
on one side and the out on the opposite side? I have attempted to include a
link that shows the assembly.

Any help would be appreciated.
