I ran an Auromotive A750 on my wife's 68 Firebird with -6 lines to the reg and back to the tank. We ran a best of 10.83 with that setup. Tank was sumped with a -10 feeding inlet side of 100 micron filter. 10 micron at carb. -8 from reg to carb. Engine was around 600 hp 600 torque. 950 quickfuel carb.
You want 10 micro at carb, not 35. Fuel pressure set at 6.5 to 7 psi. I run 6.5 psi. Follow the manufacture recommendation for line sizes. If you put a -8 on a pump that requires a -6 supply, you will be loading the pump up current wise. It puts too much head pressure on the pump supply making it work harder, and can cause fuel delivery issues. I used a teflon liner braided hose good for fuel.
