Question on suction hose

NCMau · Apr 22, 2012

I have to replace the power steering suction hose. The suction and the pressure are both 1/2" hoses. I would like to use a 3/8" for a flexibility issue and leave the existing 1/2" pressure hose in place. I realize that normally the suction should be larger or at least the same size.
My question is, since the steering is a low volume system, can I get by with a 3/8" for suction?
I would prefer to use the 3/8", but it is not absolutely imperative.

it is not something i would recommend the mfg. already took into account the low flow and used the same size hoses. if it is flexibility try gates or flexdraulic hoses

Well I didn't really think that I was going to get away with this idea. Thanks for the tip, I'll look into these flex hoses.

A 1/2" suction hose is already smaller than normal. I would not mess with it. If your pump can't get enough fluid because the input hose is too small, you could be looking at some very expensive pump repairs.
