Quick question I am planning on doing my entire fuel line one day front to back replacing the old 5/16th fuel line to 3/8 line. But in the mean time is it ok to keep the 5/16th line to the fuel pump and then go 3/8 to the carb? This is in a 331 stroker with a Holley 650DP carb/65 falcon. Any input would be great. Thanks.
