Thanks, Jon... what you described is exactly what I did. When I did it originally, one leaked, so I tightened it pressed on the pedals a bunch, with no problems. After I did the first engine start last weekend, though, I noticed a couple drops on the floor from both sides, so I was probably pushing harder.
I'll take them out and clean the threads, but will be looking to use something more "robust" on the threads this time.
