I finished installing the "oops" fittings and performed a leak check. This involved setting the regulator on my air compressor to a very low setting ~3-5 PSI.
The first leak check showed one of the rear fittings bubbling. This was really disappointing, simply tighening the fitting didn't help, it required more grinding and smoothing. I then had to go through the process of rinsing out the fuel tank all over again.
The second leak check went well. The fitting the I reworked only required very light finger tighening to get a good seal.
