no they go into the front of each carb just above the mounting flange
so far im not happy with these demons nothing but headaches.
but i had bought them back in 2008.
and didn't use them until a few months ago.

it didnt happen over night it just kept getting milkier and milkier
most of it from flooding during tuning stage. (did more last night)
they seem to be working as the car pulls stupidly hard now.
ill replace them with fresh lines and see if they start building up again.
if it does ill simply go smaller diameter and coloured. (canadian u eh?)
