This Carburetor will operate suitably with fuel pressures ranging from 1-1/2 psi to 4 psi, with a desired setting of 2-1/2 psi to 3 psi. Fuel pressure from 4 psi to 7 psi will cause the carburetor to run excessively rich and may cause flooding. Flooding or leaks caused by excessive fuel pressure do not indicate a faulty carburetor. A fuel regulator such as # 560-58500 must be utilized in order to keep proper fuel pressure at the 1-1/2 to 4 psi range.
There are no provisions for a vacuum advance line. Ford & Mercury engines 1949-1953 using stock distributors will need an alternative place to connect the vacuum line.
