Looks like these fittings would work for adapting to -6AN.

I have already ordered those two fittings from Summit, I was planning on using those to attach my existing TBI lines that normally go into the TBI unit to the Corvette regulator/filter combo, but now thinking I might just use those fittings to connect to the sending unit/pump and go from there.
Don't want to try and cut/modify existing fuel line as I have never done so before. I would rather spend a little more $ and replace with braided 6AN hose and not be worried about whether I did a good job or not on modifying existing line.
