How long of a pice will I need to go from the mechanical fuel pump to the carb thanks

 

50" should do the trick. 40" might but maybe not. Since sticks of that stuff come in 10" length increments, you'll be cutting and re-flaring it regardless of what you buy, so just make sure your piece is "long enough". You'll be bending it as well. So you'll need a good tubing bender (can't just reef on it by hand, you'll flatten it), a tubing cutter, and a double-flaring tool. Don't even TRY to do that job without those tools.

Buy acoupla sticks of tubing: odds are, you won't get it quite right the first time; but you can take what you observed and improve on it the second. That stuff is SOOOOPER CHEEEEEEEEEP so it doesn't too much matter anyway.
