Stretching my wheel base a bit and I am using a 2011 F350 Sterling rear axle so a but more beef. Relocated the cross member on the frame and this is how the tank turned out.
Now would be a really good time to add a vent bung next to the fill tank inlet. Something that will support a roll-over vent valve. If you look, your Wild H fuel pump assembly "vent" port is going to end up lower than your gasoline fill level. (don't use it!) If you run an evap line, or if you want to vent your tank...you will want your vent port HIGHER than the liquid level.
It's one way to keep liquid out of your charcoal can, and keep your garage from stinking overnight...
(not fuel supply, not fuel return....but vent.)
