Hi Guys (and Gals) - I am kit bashing a 4 Star 120 and I have built an engine cowl. The cowl is covering an inverted Saito 150 GK with the Slimline inverted Pitts muffler. I am using a 3 line fuel system. Line 1 from tank to engine, Line 2 from tank to Slimline Fuel Dot, and LINE 3 - Well this is the question????

I don't want to have a loose fuel line hanging down under the plane to disconnect when fueling, and I don't want to run enough fuel into the muffler to have it show me a full fuel tank by running out of it.

What I have decided to try is: I have fit two plastic fuel nipples through the bottom of the engine cowl next to each other (see pic). I have ran the vent/pressure line from the tank to one nipple and ran a short line from the mufflers pressure fitting to the other nipple. I then have a short line on the outside of the cowl connecting the two completing the loop (they say a picture is worth a thousand words, please see pictures).

To fuel the plane all I hope to half to do is use the fuel dot to fuel, disconnect one side of the outside loop, and wait for the tank to fill and blow excess fuel out the open nipple. All I have to do then is reattach the hose to close the loop again.

Is there an easier way that will still keep the lines fairly well hid??
Is this to much line length to maintain good tank pressure? I figure if I have several oz of psi at one end I should have equal psi at the other.

So what do you all think, Yea or Nay
