Tunnel Ram and Mechanical Fuel Pump Question #1378104 01/29/13 01:38 PM 01/29/13 01:38 PM

I have 3/8" pickup and line from the stock tank to the carb. Or, if the Carter M6903 isn't up to snuff, is there another mechanical fuel pump that would do the job? Any real world experiences with something like this? I don't want to run an electric pump for a variety of reasons. Thanks!

If so they will feed a NHRA legal 1963 550 HP M.W. motor sucking through the stock 5/16 O.D. fuel line with a 3/8 pickup in the tank Been there, done that years ago Mr.Cab Racing and winning with Mopars since 1964.
