OMC used pressurized 2-line fuel tanks from 1949 on the Johnson 10, through 1959 on the 5½, 10 & 18 (the 7½ was gone after '58). The "deluxe" 35s (Lark, Golden Javelin) used a fuel pump, & by '59 all 35s used it as well.
The OMC Accessory catalogues showed that pressurized fuel tanks were still available new through the entire 1970s. They were a continuation of the 1958/59 style tanks but also included a glass sight with a fuel gauge, and carried the OMC Accessories decals. Although the price appeared twice as much as the non-pressure tank, it included lots of hose. You had to buy the hose separately for the regular non-pressurized tank, and that will bring the prices closer to each other.
I should have bought a couple of pressure tanks back then.
It's funny, but Gale (Buccaneer) was the value division at OMC, yet they started offering fuel pump kits as an option for their 12-hp motor in 1954. They used a single line & no pressure, yet OMC was very mum on the feature while they rolled it out on Gales & other department store brand outboards.
The first motor Gale made standard with the fuel pump was the 1955 Gale 22 horse.
at 275V Points look new or certainly useable.
