I can say I have never seen an issue myself but I won't say it can't because I can't say for sure.
I used to work for Mercury Marine/Mercruiser in the maintenancedepartment and galvanized is what we had in the entire building, even on all three paint lines. We was running 160psi if my memory is correct.
When I opened up my mattress company I used galvanized throughout all the manufacturing area and on all the pneumatic operated machines/cutters . I never saw anything from the inside of the lines.
We ran galvanized in a buddy's body shop and he never had issues with it.
I will note that all this was 1988 and before with American manufactured pipe so maybe things may have changed with all the imported pipe.
I will call my buddy that owns Kicker Corporation and see what they are using since they moved in to a bigger set up about 5 or 6 years ago.
