Hey, so I got everything put on my bike except for hooking up the fuel line. I have a Grubee Skyhawk kit. I just don't understand how or where the tank hooks up to the carb. They say to get a 4.8mm fuel line but the hole on bottom of the tank is way bigger than a 4.8mm tube could satisfy.. PLEASE HELP!! Any input, greatly appreciated. pLease dOn't Laugh.
