I'm replacing my automotive Holley on my 351w ford commander with a marine Holley 4160. Can someone tell me the inlet thread size on the Holley and what kind of fitting I will need? The automotive holley that is currently installed has a barbed fitting going into the inlet on the carb with a rubber fuel line from the fuel pump. I'd like to replace that rubber line with either a hard fuel line, or a braided marine approved line. In either case I'll need the correct fitting to thread into the carb inlet and I'm unsure what thread size it is and a good place to get it. Thanks.
