Re: FUEL LINE to FUEL PUMP QUESTION - '66 425hp
if you in fact have a 66 425 fuel pump, it sounds like you have a 67 427 fuel pump to carb line. the 66 fuel pump line is bent on a 90 degree angle down at the fuel pump. the 67 lower end of the line doesn't have a 90 degree bend so the 67's do need a fitting between the fuel pump and the line to the carb. since 66 425 fuel pumps are unique , originals are very scarce and a lot of folks use a 67 fuel pump and 67 fitting/fuel line to carb. i have the original pump off my 66 425 but since i wasn't successful in finding a 66 bbc pump, i used a 67 bbc pump(which are or were plentiful back in the day) along with the 67 fitting/line. the judges are aware of the above switch-a-roo. mike- Top

jim: i apologize as i got it ass backwards(shouldn't rely on memory) . anyway, the 66 425 pump utilizes a brass 90 degree elbow. the pump end of the 66 fuel line is not bent on a 90 degree angle. with the 67 BBC, the fuel line is bent on a 90 degree angle and threads directly into the 67 pump . sorry i confused you. if u pm me your email address, i'll send you a picture of the original pump off of 66 425 vin 18057, an AO smith body that left st louis on march 22, 1966. mike- Top

How about posting it here so we all can see it? Inquiring minds want to know and all that!
