The UPS man dropped of my parts I ordered from Ground Up today. I bought an imported 18 gal fuel tank and a fuel tank sending unit. I just opened them up to look and check them out. I have a few questions how does the sending unit attach to the tank? There are no bolt holes in either the tank or sending unit? Also is there supposed to be a gasket between the tank and sending unit. There was not one in the box. No instructions either. I guess I will find out a little more when I drop my old tank and see how the sending unit is held in place. Just trying to get a heads up. Thanks guys.
