Guys,

I have a DL-50 for my first gasser, a 30% Extra 330L. Still in the assembly stage. THis is a long thread and I tried looking awhile and also tried the Search feature, but did not find an answer to my question...what size tubing (inside diameter) do you use on this engine? Funny how the instructions don't even recommend a size. I know it should be Tygon, but should it be 3/32", 1/8", or 5/32" inside diameter? I see Dubro offers those three sizes of Tygon. Thank you. Jon
