From the picture it looks like it has an electric fuel pump. I don't see a mechanical pump and the fuel line follows the heater hoses. What is the fuel pressure? There are only a few electric pumps sold now that produce carburetor level pressure. You have to look carefully at the catalog entries to find one that puts out low pressure. With either carburetor you may have to either replace the pump with one that puts our low pressure or buy a pressure regulator. I know that eight pounds will flood a pair of 228 Zeniths -- four pounds at all is fine. New reproduction mechanical pumps of any brand are a crapshoot.
