Questions: I need to plug the fuel line connector because I'm hooking up a rubber fuel line to where the original drain plug is now. What size and type of bolt do I need to plug the fuel line hole?

Questions: I have a '42 willys jeep that has the large tank. I am fixing it up for fun with my grandsons but am not willing to spend nearly $500 dollars for the original size tank when I can get the smaller tank for less than $200.00. If I put a rubber filler hose on one of your smaller tanks and modify the side of the jeep for a filler cap will it be in the way of the seat? Thanks, Jim (have ordered items from you before)
