The following series of images show the gunner side fuel tank with all of the components progressively added. Figured they might be of interest since almost all of the T-16s seem to have an alternate fuel system from what they were designed to use, especially the Swiss modification of a single large fuel tank in the rear over the tracks and differential.
First image shows the fuel tank inside its protective liner with the top of the liner not yet installed.
Next we put the top of the liner on, attach the sender and fuel line, and then bolt on the fuel tank hold down bracket. It uses a bolt at the back to press the bracket down and it has two threaded rods at the front to pull the bracket down to a mounting point on the floor of the T-16. Its pretty close to how the manual shows it but not perfect.
A locker gets bolted to the top of each fuel tank hold down bracket and the fuel tank filler comes up through the bottom. The back of the locker is angled to provide clearance for the rear bolt in the hold down bracket.
This shot simply shows the locker with the lid closed. The four raised squares on the lid are for holding a seat frame in place.
And lastly there is a shot showing a seat cushion on top of the locker. I still haven't build the frames for the seats as I am sorting out how much space is needed for the 4.2-inch mortar bomb racks which will be over the track sponsons. The upper cover for the engine housing is sloped so the cushion can hang over the locker but the angle of the shot makes it appear to be in the way. Surprisingly it all fits fairly well but there won't be a lot of space for people once everything else is bolted up.
This final shot shows the fuel tank and locker on the driver side of the vehicle. The locker is virtually identical to the gunner side but it has a divider and a place for very pistol cartridges. As if sitting on top of the fuel tank wasn't bad enough, they had to build in a place for pyrotechnic devices which point downwards at the tank.
