Fuel System and ABYC Standards
I just have a quick question regarding fuel systems and the standards put out by the ABYC. I'm going to be redoing a few sections of my fuel system, including a manifold for distribution to the main components (the engine, polishing system, heater, pump). Having experience with hydraulics, I feel compelled to use the JIC 37 flare for this piece of hardware. I realize this is overkill, but 1) I already have a bunch of the fittings and solid tubing available and 2) have the experience to make a reliable system 3) I enjoy the safety factor involved with overkill. Dont worry, I realize it is important to maintain flexible hose for the manifold to engine connection.
I have access to 316 stainless tube for the fuel. ABYC puts out a rule that states something along the lines of (this is the Transport Canada version, but you get the idea):
7.4.4 Every metallic fuel line:
1.shall be made of seamless annealed copper, nickel-copper, or copper-nickel;
2.shall have a minimum wall thickness of 0.75 mm (1/32 in); and
3.shall be galvanically protected from the structure in aluminum hulls.
I realize they dont make rules to cover every situation - but is there an actual reason why they dont specify stainless steel as OK, or am I just overthinking it?
Thanks for any input.
