i remember when i bought my first landy in SA a few years ago now. had to push it to the servo and fill the main tank up , only to find out it had a bloody BIG hole in it so i ran it on the aux. tank for a few months till shody welding split and that too was RS. solution , 20Lt jery can on roof with siphon hose direct to carby. that worked well till forced to sell 6 or so months latter. cant remember though if it was a series 2A or 3 swb
