Interesting! Very interesting! Evan, aka Coilover, posted a thread several months ago about fabbing a fuel tank also. Coilover, too, is old school, only he knows how to spell it! I'll dig it up in the archives and let's compare them! Old School vs. Ol' Skool! Found the thread. https://talk.classicparts.com/showthread.php?t=6010
How much is in the tank Its easy to work out capacity of a tank in liters, you then you can convert to US Gallons 100mm or 10cm cube is 1 liter of liquid = .264 US Gallon. For people not sure on metric 100mm or 10 cm = 3.397ins, 1 US Gallon =3.7854 Liters Old enough to be taught in Imperial but now work in Metric and believe it or not it is a lot easier Gerald
Now time to work out a mount system. Got the sender installed. Going to NAPA to get 1 1/2 fuel filler hose and new tubing to extend the fuel line.
We cut the hole to size, then stacked a 1/4 inch piece welded underneath to give it some meat to screw into.
