Need some help. when building my Suburban I installed a late model 31 gallon tahoe/suburban tank betwen the frame rails behind the rear axle. I forgot about venting it. It takes forever to fill it up with gas. The gas sloshes out of the filler tube if I go too fast.Is there a way now to vent the tank? Can just the filler tube be modified to vent the tank? Should have remembered about venting before installing the tank.Not a big deal but I would like to be able to fill the tank faster. Any advice?
