Some of this was definitely due to overfill running into the wing cavity. But when it seemed to occur lately without any spillage at the filler, I drilled out the inspection plates over the fuel senders as a first step. There was evidence of seepage from the mounting screws, running down the back of the tank. I withdrew each screw in turn and coated the thread / washer (serrated)/ head area with a fuel safe gasket compound and tightened them all back down. the rubber gasket did not appear to be a problem. The lockwashers used are quite open and not what I would have expected in this area. I dont know if this is the end of the issue. It had been occuring mainly when the tank was kept full, suggesting that if there is a leak its likely near the top.

All engine control cables have been run through the firewall, but I haven't (And can't at this point) installed a cabin heat duct. Here's where I get into a Catch-22. I built my fuse on a rollaway jig and can't hang the engine until I attach the last skin and remove the jig, leaving the fuse on the gear.

What I'm about to say won't help those who currently have problems one bit, but it might help those in the process of construction. I strongly recommend, after installing the fuel gauge sender, but before installation, doing a tank leakage test. It's fairly simple to connect a source of air to the port for the quick drain in the bottom of the tank, and to apply a few pounds (not many!) of air pressure. Swipe some of your wife's (or, if you're female list members, borrow it from yourself) liquid dish soap. Put it in a small container, and add a little water. Make a water-soap mix suitable for blowing soap bubbles. Brush the mixture around every possible seam in the tank, around fittings, and especially around every possible opening on/around the fuel sender. Don't be surprised if you get some bubbles, and have some leaks to fix. They're easier to fix now than later. My tank was good, but my fuel sender installation had to be redone, and sealer applied at several points. That's my free advice for today. I remind you as always that my free advice (or anyone else's) will be worth as much as you paid for it ... if you're lucky. -- ============================================ Do not archive. ============================================ Jim B Belcher BS, MS Physics, Math, Computer Science A&P/IA Retired aerospace technical manager Mathematics and alcohol do not mix.

That grommet fits the HD/HDS header tank neck diameter. It was necessary to remove some rubber from the upper surface of the grommet, since the Ercoupe header tank has a longer neck than the Zodiac tank. Of course the hole in the upper forward skin must be sized to fit the periphery of the Ercoupe grommet. My project is still unfinished, but I know from experience that the grommet keeps fuel from leaking around the Ercoupe's filler neck. Hope this is helpful.
