The sc400 fuel hanger was designed in a fuel tank with a seperate access panel, so instead I bought a EK Civic pump assembly and married the two. The level sender is just some generic unit that has the ohm specs needed to run with the Knock-off Smiths gauges.

The mount plates were a pain to make as the mounting holes were not spaced evenly, in hindsight I should’ve used thicker steel too. 18ga was used on the fuel tank throughout but 16ga would've been easier to work with.

The internal baffles didn't change much besides a couple additions around the pump. I filled it with water and was happy with how the baffles were working.

The mount plates were welded all the way round on the inside, the plan was to weld the outside too but the heat distortion threw the entire panel way out of whack. It took a few hours with a torch and Mallet to bring it back to flat-ish. As you can see there's still lots of distortion but it's going to be covered in sound deadning and under a false floor anyways. What I should've done was strengthen the panel prior to welding, a few bead rolls combined with some horizontal bracing would've gone a long way.

Used POR15's tank sealer to deal with any pinholes and inhibit rust. After that its primer and seamsealer (closer to butyl tape then rubber) around all the edges, the idea being to mitigate spillage if a crack forms during an accident. Also fiddled with the roof placement to get it as low and forward as possible.

Started work on the roll bar mounts and trunk frame, the fuel tank will have 2"x1/8" straps. Good isolator pads seemed impossible to find so Big rig mudflaps are going to be used as the interface between all the parts.

Not sure if a bar linking the horizontal rail down to the panhard area will be necessary, its going to get a steel panel regardless.
