Next up was the fuel filler tubes and caps! We took heavy inspiration here from Sean's build and used 2" stainless. (aluminum is out bc well..... you all have seen my aluminum welds)
First I mocked it up using the 3D printed modeling blocks I posted about previously that were intended to be used for the exhaust. Luckily I had bends already printed that were 3" CLR so they worked great. Sadly I completely neglected to take a photo of the mock up. It made it really easy to cut out the exact bends we needed and tack weld the pieces together.
We mounted the tack welded pipe to the tank and then drew a circle around the filler cap with it positioned exactly how we wanted it with respect to the fiberglass body. This made it easy to fabricate a perfect flange to position the filler pipe where we wanted it.
It was a blast TIG welding these, and the purge system we cobbled together worked great. Definitely a confidence booster we can pull off welding the exhaust up as well.
We also went ahead and installed some tank vents.
In the future we will install a seal between the filler neck flange and the filler cap so that there can't be any leaks in the event of a disaster...
