<DIV>I have been using a two line system and my colwing is already setup for a two line. The vent line is the overflow and runs to an L in the cowling. The main line with the clunk runs to a fuel filter and then the pump on the webra. I have a break in the line between the clunk and the pump. This break consists of two Ls and a piece of fuel tubing. I have been breaking the line to fuel/de-fuel the plane. That way the pump and carb on the Webra was not getting flooded during fuelings.</DIV>

<DIV>Would this still work for the perry V30? Just run the line from the fuel filter to the perry pump and then from the perry pump to the needle valve?</DIV>

<DIV><SPAN class=627222014-27122004><FONT face=Arial color=#0000ff size=2>Yes, D&T the backplate to supply power to the pump. If using an OS160, there is a neat fitting available from OS that replaces one of the backplate screws and provides a pressure tap. It requires drilling into the bottom of one of the backplate screw holes, but is a really slick installation.</FONT></SPAN></DIV>

<DIV><SPAN class=627222014-27122004><FONT face=Arial color=#0000ff size=2>I use a three line setup. One line with a clunk that goes to the pump. Second line with no clunk pointed into the bottom rear of the tank for fueling. Third line for the vent/overflow. You cannot fuel/de-fuel through the pump, and if you put a T behind the pump, you will force fuel through the pump while fueling. So, the three line makes the most sense so that you don't have to disconnect a fuel line for fueling.</FONT></SPAN></DIV>

<DIV><SPAN class=627222014-27122004><FONT face=Arial color=#0000ff size=2>The vent/overflow simply gets routed to the exterior of the plane. The VP30 does not use a pressurized tank.</FONT></SPAN></DIV>

<DIV>As my excelleron is ready for test flying, I am making preparations for re-engining the Focus 2. I am trying to thinking through the setup and plumbing for the use of a peryy pump, specifically the V30.</DIV>
<DIV> </DIV>
<DIV>First need to tap the backplate for crank pressure, then ?</DIV>
<DIV> </DIV>
<DIV>Would a two line system work? What about the overflow?</DIV>
<DIV> </DIV>
<DIV>Would a three line be better? How would you set it up?</DIV>
