Because today's gasolines evaporate at a lower temperature than when these cars are new, an electric pump is often used to give a slight boost to fuel pressure in the system. This keeps pushing gasoline when it begins to bubble from the heat and normally keeps enough liquid flowing to make sure the engine runs. Another thing to check on any 1952 and earlier 226 engined K-F product is the carb pre-heater thermostat unit on the exhaust manifold casting below the carb base. If you check the Kaiser-Frazer Service Manual, you see what I am talking about. Over time, the assembly tends to rust up in the open position, directing hot exhaust gas up into the carburetor itself. The assembly should be in the closed position for normal driving. The feature was dropped for the 1953 model year.
