I bought a roll of 3/8 aluminum fuel line from Summit. I want it to connect to the factory fuel sending unit. Can I use my double flaring tool with a regular steel flare nut? I've never flared aluminum tubing before. It seems like it would be fine for as soft as aluminum is but figured I need to find out first. I hate to go buy AN fittings cause they're expensive.

The usual way of using aluminum tubing is to use 37 degree single flare and AN type fittings. Aluminum does not flare to 45 degrees or 45 degree double flares very well, usually it cracks or ends up obviously too thin.

With the methanol in todays gas, I would never use aluminum for fuel in a street car, only stainless.

Thanks guys. I won't use the aluminum then, but I have to ask why a Holley carb float bowl is not affected since its aluminum also???? Not being a smart @$$, just trying to understand

unless you get one of the new lightweight holley carbs the bowls and main body are actually a die cast zinc alloy material. and over time they will develop corosion from methanol. ask any racer who has run methanol and neglected to clean out his fuel system.
