Aluminum fuel rail - anodize necessary?
Aluminum fuel rail - anodize necessary?
(OP)
Hello all -
I recently upgraded from a -6AN fuel rail to a -10AN fuel rail. I am making the -10AN from an extrusion I bought since no one makes a kit for this vehicle.
I plan on only running 93 octane pump fuel regularly, with up to C16 fuel (leaded) when I dyno/track the car.
I know with methanol/alcohol anything aluminum should be anodized, but what about conventional fuel or race fuel?
If it's not necessary I will not do it. I powder coat the exterior of the rail so I end up blasting that anodize off. It's the inside I am concerned about - the -6AN rail I had was clear anodized inside. It's relatively expensive to get one part done and I don't have others to do. It will also take a bit of time in my project.
Any help? I do not plan on running the car on E85, alcohol, methanol, etc., only unleaded usually and occasionally leaded fuel up to C16.
Thanks!

It is not a normal road car though, I do not know how well it would handle road salts, etc.
My rail is made from 6061T6.

See: htt
So if you can guarantee that your fuels will never have methanol in them, there's no obvious need to anodize to protect the interior of the rail.
