Fuel line ?
Anyone actually know the requirements for fuel line between the pump and carb (high pressure side)?
USCG Title 33 CFR Sections 183.501 - 183.590 states the following 183.562 - Metallic fuel lines (a) Each metallic fuel line that is mounted to the boat structure must be connected to the engine by a flexible fuel line. FEDERAL LAW 183.558 - Hoses and connections (a) Each hose used between the fuel pump and the carburetor must be “USCG Type A1” hose. "If a hose is used in the fuel line running between the fuel pump and the carburetor, the hose must be “USCG Type A1” and so labeled as required by 183.540. This requirement is applicable whether the fuel pump is engine mounted or mounted remotely from the engine, as permitted by 183.566." If this is all true, why does all the stock merc motors use what appears to be soild aluminum lines with flare fittings? I want my boat to be compliant, I don't care which one it is. |
you ca nuse rubber or steel/ aluminium. merc uses them for supply and part stocking reasons i would think, as well as for value. there are a number of ways to use a flexible line rather than rigid, just make sure you choose what is thje rite inside diameter.

you got it right there: "a) Each hose used between the fuel pump and the carburetor
must be “USCG Type A1” hose." There's no USCG req that it be metal. I paid my local Industrial Hose $0.57/INCH (just happen to have my invoice right here) for -6 hose (plus more $$$ for fittings) that actually has the Type A1 stamp on it. Then I found a guy that would bend a $3 metal line for $20; I bought two lines so he could practice. :D This was Thanksgiving Friday and I was running around trying to make sure I could boat that weekend. |

I'm doing it now in preparation for Memorial Day, even though its 3 weeks off! |
Two attempts for me bending steel fuel lines ended up with me throwing away two steel lines. And that was with me buying the tool to make the bends, not that I'm having too damn much success using braided lines and A/N fittings. See my post.:(
