elbows or any type plumbing on the intake side have just as much restriction
as they do on the output side.

but a single 90 isn't going to cause enough loss to make it not worth while
to get your pump in a position you prefer.

Thanks guys - I finally hooked up this pump with 1" bulkhead,
than 1" MPT - 3/4" barb hose adaptor, then a piece of soft
vinyl 3/4" ID hose and then 3/4" barb to 3/4" MPT 90' elbow
to the pump so the pump is parallel to the sump side wall.

BTW - I am going to use the same vinyl hose for a return line.
Is vinyl safe for marine fish tanks? It is nice black so I like
the fact it will not cover with algae from the inside, but I am
not sure if vinyl is not leaching anything to water...
