The modified fuel tank for the GP-12 wasn’t an easy change. If one is doing an original M-I RS-3 the Bachmann model fuel tank is perfect. However, if you’re doing a GP-12 the fuel tank was enlarged by the MP and the metal casting on the frame of the model needs to be reduced so it fits. I had an Exacto metal cutter I put in the Drill press and spend 45” cutting away metal so the rebuilt fuel tank would fit (fortunately I still had my fingers intact after this). There is probably safer ways if one had access to a milling machine. Be careful on this part or just ignore it completely if you don’t have the right tools.
Good news is the original air tanks are the correct length. Details Associates part FU 3102 gives the fuel filler pipes, and two different sight gauges to detail the tank.
