have a question for all you 71,73 gurus, have a fresh 351 Q code just rebuilt. put in a carter m6882 fuel pump from CJ's pony parts. running original 4300 carb. when car was started and running at 1600 rpm to break in gas was flowing out of the carb. the guy who rebuilt the carb said the 4300 should only run on 3 to 4 psi ford says 5psi, the pump says 5.5 to 6.5 . is it the carb or the fuel pump? thanks guys
