I still couldn't located any sweeps that would fit the DWV pipe for my rigging tubes so I went with the two 45's. If this doesn't pass inspection then I will have to scrap the tubes altogether.
Since it was locked in place I had to pick up this wire saw to cut the fitting out.
Fitting replacement with two 45's
With the help of a friend I dropped the new fuel tank in place. I used neoprene on either side to protect the tank from the unistrut braces that I will bolt it to.
As recommended I also used the 45's where the tubes will come through the deck under the console. The 45's allowed me to rotate the fittings so that they are offset and get them closer together. The marks you see were from the test fit prior to gluing together.
