Pre Bent Fuel Line and Sub Frame Connectors

I was planinng on using pre-bent but due to the sub frame connectors it appears these line will not work. I would have to cut the lines to them through the sub frame and up to the engine.

What is a good solution?

I was thinking of using SS Flex line and fittings. How do I connect AN fittings to the stock sending unit?

I am not sure how to proceed?!
