Bill, that's the correct tank. However it should be re plumbed. In addition, NO Perfect tank has it's pickup tube soldered internally therefore it's a tuning fork inside the tank which fails from vibration. This means that looking at the feed line, it usually follows the same angle and it's terminating at the bottom of the tank which ultimately has an impact on tank height when flying inverted vs upright. Once inside the wing, there's no adjustment. Re plumb the tank so that the pickup exits the bottom of the tank and keep it very tight to the bottom of the tank. Solder it entirely to the bottom and leave enough protruding to fix a piece of tubing. Internally solder the pickup so that it's centered in the wedge. I would keep it slightly off of the rear of the tank as well. about 1/8" Remove the vent out of the bottom of the tank or solder it closed. This will prevent it from tearing out on a belly landing. Even though the JR has a piece of ply on the engine nacelle, any pipes protruding straight down offers themselves to be broken off. Re plumbing as I mentions shortens the length of fuel tubing and the craziness of the fuel going up the pickup, down the front of the leading edge and back up to the spraybar. The tubing being that long and considering the type of flying that the JR offers will cause some issues in the hard maneuvers. With only one vent pipe, you will increase fuel draw and prevent siphoning. Fill the plane holding the plane engine pointing up and fill through the pickup until it comes out the top vent. Cant the rear of the tank as far outboard pushing the front of the tank's end cap into the center rib. If needed, you can also sink the end cap slightly into the center rib. This will insure that all fuel is used up. Ken
Looking at your bellcrank and lead out wire termination I see your using braided cable. I lost my Jr Satan last year at the Garden State Circle Burners Combat event when the bellcrank cut the up line slamming the plane in. It was quite disturbing and I decided not to rebuild. I hope you deburred or bushed the holes
