However adjusting the fuel vent tube so that you only fill to 15 gal on some (most) models. See the link below to learn more and get instructions for modification.Just FYI aaron www.4x4wire.com/jeep/tech/fuel/15to20gal/www.jedi.com/obiwan/jeep/15to20gal.html I'm going to try this on my YJ. Looks easy enough.
