snorkel tube size?
So im looking at makeing my own snorkel out of some pvc pipeing and a couple of silicon elbows as to buy 1 for my td is well out of my budget! now i've been to bunnings and i can get 40mm or 80mm tube.... would the 40mm be to restrictive? has anyone else made their own snorkel? whats the diameter of a bought snorkel?
