The most fool-proof way I've checked fuel lines for miniscule leaks is to disconnect both ends, cap one end securely, and apply a vacuum pump with a shut-off valve and gauge to the other end. Pull a vacuum, close off a valve between the pump and line with a gauge between the valve and the line, and check it again after a few hours to see if it's loosing vacuum. If it holds the original vacuum overnight, you're surely OK.
