mild/moderate 318 but I've upgraded my entire system to 3/8 line (thanks all for help with the fuel return setup). The stock pump is 5/16 so that ain't happening. The only thing I've found is Eddy's replacement for $137.00. I don't need a race pump as this is a street car. Whats out there that'll work, don't worry about connections as my toolbox runs the gamut.
