I'm not trying to make it look really professional, just something safe and will last a while.
I was thinking about getting a THIS
or something simular to tap into the line that already leads to the Carb. Then I would just run a new line to the new tank. I would use a petcock and maybe an inline fuel filter from the secondary tank.
I guess my only issue is all the car part fuel line things seem to be 1/4" in size and it seems my carb wants 1/8" lines...
And then of course I'll have to find a tank....
Thanks for the reply, maybe someone else has had to do this and will post what they did for this problem.
