Hi Delta.
Some one else used the methanol in the truck, not me. i'm just the person
sorting out the problem.
It would be the standard rubber components used in air brake valves.
( seals, O-rings etc ). so i'm not sure of their properties or if methanol will affect them. But as i said in one of my earlyer posts this problem has only started since this person has used this in the air system.
Clive.
