| I understand the An fittings with PTFE line... What is the best way in-tank...from pumps to external? Planning on dual pumps in-tank. I have seen pics with simple screw clamps (from in-take filter to pump), one pic used a nylon/teflon "Y". Once out of tank, top sending unit...AN fittings as normal. Any issues clamping the PTFE with simple screw clamps? Thanks
