1963 5.5hp pressurized tank or not??

[mikerooney]

I have a 1963 Johnson 5.5 hp Sea Horse and I need to know if this motor requires the pressurized fuel tank to operate. I'm told that ended in 1960 but the fuel line is a 2 hose setup. Also, does anyone rec a good online site for buying tune-up parts and maybe a manual? The model # is cd20c and the serial is 2325318

Thanks

Mike
