Hi, I bought a m371 6 month ago and used it to re-do my patio. Now the work is done and I fell love with this little machine and am in the process rebuilding the engine. Once this is done I'd like to rebuild the rest of it, like new bushings in thlift arm, etc. The gas tank is completely shot (lots of holes) and the last owner installed a plastic fuel tank right behind the driver's head (I really do not like it) and gravity feed. I checked with the dealer and they told me the little tin tank will cost me $400. Is there other way? Thanks. Erwin
