I wouldn't concentrate on the return lines, but rather check all potential sources of air intrusion. Fuel heater O-rings, WIF sensor, return lines & caps, etc. You might save yourself the hassle of doing return lines. Or you may find that the return lines AND something else are letting air in.

1990 Jeep Wrangler Sahara, in the process of a major overhaul/upgrade. OM617 on the horizon! Front & rear Dana 44s from a Wagoneer till I get some 1-ton axles built & narrowed, and eventually a front shackle reversal. Diesel YJ, bay-BEE, and not a cookie-cutter 4BT conversion!
