If the module seals are in good shape and not leaking, you can shorten the lenght of the main tank vent located to the rear of the tank. You'll have to make the cut from the inside, shorten the vent tube to about 1-2" from the top. This will allow a few more gallons to be filled into the tank. Sometimes the roll over valve on the top of the module won't completely seal, so I used a section of rubber hose and routed it up with the main vent/filler neck. This will allow you to fill the tank completely without leaking fuel all over.
