I have to run all new fuel. Need ideas on what to use, rubber, steel, aluminum or nicop?

I ran the NiCop in 3/8 from the tank to the fuel pump.
Different opinions but Aluminum does not have the best heat and abrasion, Steel would work well but harder to bend and rust over many years (our cars in much better conditions than 340 years ago as a daily driver) stainless even harder to bend and resists flaring etc if you wanted. Rubber abrasion, ethanol, and down stream of the fuel pump could suck in and have issues when aged. Just my opinion.

The issue I am working on now is 3/8" tube from fuel pump (3/8 npt) to filter and carb. I want to hardline but fitting for carb etc is getting to be a pain to find. Even looking for double flare, o-ring flare etc. Likely will use 37 degree AN tube and flare, but still looking.

This is somewhat dependent on what you're going to be doing with the car. If the car is going to be run at NHRA tracks, it needs to conform to those safety regulations, so you're looking at basically hard line for the entire system. As noted above, several options all with their own advantages and disadvantages.

Each track is going to be somewhat different, you may want to call the head tech if that's something you're going to be doing.

If this is a factory type rebuild and you're not needing to do anything specific, I'd probably purchase some pre-bent fuel line reproductions from one of the big restoration houses like Ames, Classic Industries etc. I've had use with some of these fuel lines and more specifically brake lines, and they are easy to work with and do the job without breaking the bank or having to bend your own stuff and create fittings.

I wouldn't use rubber for an entire system. I use steel or AN line for my systems.

Nicopp, I use it for all under car lines (brake, fuel, transmission cooling lines) because of it's easy to bend, double flare, and resistance to corrosion. It's not real cheap, but you'll only do it once.

Probably go with the nicop, this is a mild built 400 with 4 speed in a 63 LeMans, 9" Ford with 3.50 gears. Wednesday night drags in the summer.

IMO Nicopp is the best choice for hard line. It will last forever and bends/flares very easy.
