All dual feeds leaking. ANNOYED.

Hey there. Recently installed a QFT 750 on my car and can't get the dual feed fuel lines to stop leaking. I have tried 2 different kinds. The cheapo Holley chrome style, and it leaked at the plug for the pressure gauge and leaked where the NPT to hose barb screws into the unit. The got a russell set up and it leaked at the outlet into the bowls as well as the plug for the pressure gauge. I have been told to NOT use teflon tape as it will break down over time. Anyone else have problems like this? This is a very simple thing but its giving me hell. Im considering making my own that has flares all around. NTP fittings seem awful.

Best,
James
