Best is to modify the sending unit and drop in, down low towards the bottom with a drop pipe that either has a threaded fitting or simple elbow for a hose and clamp.

I would suggest an elbow on top, with AN fittings and hardline over to someplace on the side where it can be accessed from underneath. Or if in tank pump, the return should go in next to the out line from ehe pump mounting plate

I've put an ls2 in a 63 vert, and used a corvette/camaro ls filter back by the tank. 2 lines on the filter rear 1 in & 1 return, 1 on the front regulated pressure to the eng.
