I'd suggest taking his 265-40with a#16tip ratio, and figuring it into your 165max(blankedy blank blank)with a #12, and do the best you can with it ; )

look under the bulk tank and you will see a regulator on the pressure building side. Tighten the bolt on the regulator to give you more pressure. If the safety valve blows off,back up a couple of turns and thats what you will have to work with. I use half inch oxy line and three eights fuel line for volume. Dont be afraid to go heavy on the fuel since you will get more heat that way. If you are running a Victor HDNL tip,you can bore it out to a number 16 with a drill bit since all the HDNL carcasses are the same.
Hope this helps

As a side note: make sure you have hearing protection because the torch howls at high pressure. Do not tune the torch for a nuetral flame,just open up the valves as far as they will go and the torch stays lit with the oxy lever depressed and make sure the tip is clean. I built a tip cutter so my tips last a long time. You can cut them down to about and inch and a half long and they stil;l work
