Well what i ended up doing was sacrificing my gas gauge for now as it didnt work anyway, and made a new plate. drilled appropriate mounting holes then a 3/4" hole in the center. Welded a coupling in, put a barbed 90°fitting on top, and a fiting for a 5/16 inverted flare line bent towards opposite end of the tank on the bottom side. Should be good to go. Thanks for all the imput fellas...
