Material suitable for fuel/petrol/gasoline - i.e. carb manifold?

Hi,

(Note: ignore other duplicates, answer this one - the system told me the posts failed to submit but obviously the had :cry: )

I need to make a carb manifold and I am wondering if Alumide or some other material would work. I am concerned about it not being tolerant to the petrol in the air/fuel mixture. I have initial choosen Alumide because the manifold sits on the cyclinder head and would need to withstand ~100C without too much trouble.

Cheers,

Paul

ok - I think I can answer my own question

Aliminide is based on Nylon - googling for "nylon chemical resistance chart" shows that it is unchanged by gasoline and oil.

Let me know if I am wrong.

But Aluminide, like WSF, is porous....

thanks you just saved me a lot of wasted effort!
