Looks like a Snyder tank! This what is in our 82 310.
I needed to put a pipe coupler on the fill. It was so short that the old hose was clamped on the treads and would leak when filling and when topped off! Only fittings on one side.
That is one nasty looking tank!
Great time to replace all the fuel lines!
