The fill ports were from a LT4 lines set. I have not used reservoirs in my last 3 builds. I have usually added Jiffy Tite dry breaks to the top of the intercooler to bleed the system.

This time I made a reservoir at the very top of the system to bleed it. When we evacuated and filled the system it worked great. It is critical on this supercharged systems to get all the air out. After we filled the system we removed the extra reservoir and reinstalled the factory caps.

The easiest way to know if the system has no air is fire up the intercooler pump(s) with the engine off and listen for air going through the pump. If it is dead quite no air. You will hear the air pockets gong through the pump.

Another note. Keep the system as restriction free as possible. Don't use a lot of 90 degree fitting and extra lie length. Short runs and minimal bends..

Good luck

Mark
