I have 3/8" (stock is 5/16") lines running from and to my gas tank. I didn't drop the tank before because it's too much trouble. Question is where exactly are the stock lines going to the tank and is it possible to get to them without dropping the tank? I figure the return line could be connected to the tank up high by using an AN fitting into the tank and attach it with a good gas tank sealer. The real problem is the supply side coming off the fuel pump.
