When i got my carb remanufactured by holley, they didnt return the manifold that connects the two fuel bowls to the line coming from the fuel pump, so i had had to get a replacement which didn't line up with the old metal fuel line from the pump. I replaced the metal line with marine grade hose. Am i still in compliance with USCG regs? The only relevant reg i could find was 183.558 which states: "(a) Each hose used between the fuel pump and the carburetor must be “USCG Type A1” hose."

I'm pretty sure i'm in the clear, but is just wanted to make for sure. Can anyone elaborate on this?

Thanks
