This particular fan unit came with 6an. I use all Earl's AN hose and their fittings. With the subframe connectors, there was no clear path for the hoses to get to the rear without looping them above the trans crossmember. I didnt like that technique, so I bought some frame pass-through fittings and now they go through the crossmember brace. The photo below are my fuel pass-through fittings, but the concept is the same. Tough to get a good photo right now without lifting the car up
