Thanks,
Not tieing off the tube fittings , sure the stopper is installed correctly, but with the dead sticks I had last weekend with my trainer, makes me wonder if something fuel related is going on. Not sure, but for this one I'll tie the fittings. I like the sullivan clear tanks, but LHS doesn't carry them, there is no doubt with them that the piping is right and it's easy to see the clunk. I just finished cutting out the cowl, doesn't look too bad for a rookie. But could've done better.
I've been using small wire ties both inside the tank to affix the tubing, and to prevent the tubes from moving when I screw around with the lines.
This seems to help a lot and was suggested for gasoline engines too.
When you assemble a new tank a good idea is to blow into the CLEAN tubing with the other side stopped up, and spray the tank with windex, etc...
Look for any bubbles or seapage.
The plastic flashing on the cheaper tanks typically causes problems as it creates an area that lifts the stopper even when compressed.
I usually use fine sandpaper to clean out the flashing around the hole, then flush the tank with windex, let it dry, and finish with another small flush of glow fuel.
Good info,
I checked out the tank how too section here on the forum. It shows places a piece of metal tubing on the half way up the clunk line, Do you do that? I've never done that with any of my planes, but it does make sense as it ensure the clunk line doesn't get wrapped towards the front of the tank. Did get to run it last night, So hoping too this afternoon, have to be on a real plane for california this afternoon, so don't have much time.
