Some gas cap vents can be very subtle. Look it over close. I'm running a modern gas tank on my 56 Exec with plastic screw on type cap. UNVENTED. I drilled a 1/64 hole streight thru it. HOWEVER my cap is protected by a the fender and a service door. I donlt know what your 50 has. IF cap is directly exposed to weather with no type of protection then u'll have to get a cap that is vented for such an application.

Test current cap with a radiator hose or something and suck thru the hose from the INNER face of the cap to determine if it really vented or not.
