Metal Fuel line

[flargin]

There is a place I want to put in a metal fuel line in the boat, what should I use? I know I can use A-1 rubber, but I was thinking of something metalic


I found this description online...

Metallic fuel Lines: If you use metallic fuel lines, the ones that run from the fuel tank to the fuel inlet on the engine must be one of the following; seamless annealed copper, nickel-copper, or copper-nickel. From the fuel pump to the carburetor they can be any metal you want to use. Beware. You could set up a galvanic couple and the tube will be eaten away like powder. Choose carefully if you use metal fuel line from the pump to the carburetor. ​

is seamless annealed copper, the same as plumbing copper, I cannot find any source for it on the web sites.

What type of concern should be considered with the "Galvanic Couple" ?

Well, my Silverton has 2 tanks and 3 transfer valves, all plumbed with copper fuel lines. Don't know for sure, but they certainly LOOK like the regular plumbing-supply copper.... Maybe you should ask a marine mechanic.

As far as galvanic corrosion, if you have dissimilar metal fuel lines they can interact negatively with each other. Best solution is to insert a short piece of non-conductive (rubber) fuel line between them.
