Im goint to be building a new Intake air horn for my truck, when I do the twins. I plan on maybe one day running water/meth on it. Would anybody know what size bungs I would need to get for the meth injectors. Figured I would go ahead and weld them on incase I ever did decide to put it on my truck.

 

most of them are all 1/8 inch pipe, but there could be others

 

ok thanks man, thats what I was thinkin but wasnt sure
