Product Feed Line Sizing

[RacinJason]

So I had a car wash service company out to look over my equipment and he recommended that I increase the size of my product feed lines to my SS bays from 1/4 inch up to 3/8 inch. If I did such that I would be much happier with how everything was delivered. what are you all running out to your SS bays? would I also increase the air line feeds?

3/8 to the manifold above the boom, then 1/4 from the manifold to the gun.

Since you mention air feed I assume you are referring to low pressure poly lines. That's not a bad suggestion when you are replacing and could improve performance in the bay. In my case I use 1/4" for tire cleaner and foam brush but presoak and foaming conditioner are 3/8"

1/4" air lines are fine and supplies plenty of air for all applications IMO.
