Fuel water separator 3406b question

Hi guys and girls, quick question I have a 3406b cat 350hp 7fb the fuel water seperator has 2 ends once says “in” other says “out” which line goes to which currently I have the lift pump fuel hose connected on the “out” and the Fuel hose that comes from the main tank on the “in” is that correct? Also does it matter which side I run it?

 

Ok I appreciate that just making sure because they look cross cross instead of the tank line going straight into the “out” it loops around to the other side which is the “in” I thought it might be out of place

 

I
Yea right it through me off lol you mind me asking how you ran your plumbing? I’m trying to get it to look cleaner but can’t figure out how to do it lol

 

Ok yea that’s why I was asking if I could reverse the lines to make it look cleaner but they probably set it that way for a reason so I bet I can’t do that no worries I appreciate the help though fellas

 

Oh ok yea that was something I thought about changing the whole housing but just for some crooked style fittings it’s not worth it and especially like you said with the restrictions I’ll Stick with this
