I just did that on a 1996 Speedster. I mounted the empty oil tank and connected all the oil lines. Then I added oil to the tank and observed where they oil ended up. To the a full oil line to the RV I had to lift oil line higher than the RV connection as there was some air in the line. On the injection line, which is more critical, I removed the line to the pump and bled the air out by allowing oil to flow out of the line and I reconnected the line while the oil was flowing. That way you have a full line. Next I opened the bleeder on the oil pumps one at a time and let the oil flow a bit before tightening the bleeder screw. It wasn't a mess and actually worked pretty well. The lines from the oil pump to the engine intake were already charged. You can't see much of the oil line but this is the set up on the 96' Speedster. Good Luck.
