Adding a Suburban Gas tank

[SirRobyn0]

I have dual saddle tanks, so 20 gallons on each side. A burb/blazer tank was mentioned in my post in reference to someone mentioning using one. The setup would be almost identical. Routing the filler for a rear tank is always an interesting choice. My bed, only had one fuel door like all cucv beds. The PO routed a filler into the passenger side wheel well. It works.

I have a dump kit on the factory box so both my filler necks are in the well wells. The only thing I don't like about that is with a heavy load it can be a littler tricky to get the filler in there. Also always need to be sure any filler in the wheel well has a good cap, don't want water or dirt getting in there.
