Questions on fuel tank replacement

[skunkedskippy]

I'm replacing the fuel tank, hoses, fill, vent, etc on my 1977 Skipjack 24 open. I believe everything is original equipment. The fill is grounded to the tank, and the tank grounded to the battery, via the sender, I believe.

If I replace the tank with a plastic unit do I still need to ground the fill?

The current fill hose is clamped to a copper 90? elbow below the deck. Is copper a suitable material for fuel lines? Or, are "modern" hoses able to bend 90? without kinking?

While shopping online for hoses I noticed that most fill hoses are A2 and and vent hoses are A1. Is this considered the current "standard" for hoses? I would think the higher fire rated A1 would be better for both hoses.

Thanks in advance for your help. I'll probably have many more questions as I go forward with this project.

No, the tank is grounded to keep static electricity from building up. My opinion

Yes, there is no issue with copper, and hoses won't bend that tight without kinking

A is the fire rating, the number is the type hose. 1 = fuel line, 2 = fill hose

That's right, the number designates the permeability. So same question, why wouldn't you want the A1 for both hoses?

Thanks for the reply!

Same answer, 1 and 2 are types of hose and have nothing to do with permeability. I'm not an expert, just a guy who reads the USCG spec and this is how I understand it. Google USCG fuel hose regulations

I'll take your word for it. I must've had some bad info. Thanks for your help.
