Excellent , I could never understand why anyone would use pipe tape on automotive . You have no idea how many fuel pumps I've seen with tape in the flapper .
Teflon has no sealant ,it's just slippery , that's my usual talk I have had with customers .
I must admit to using silicone sealant , sparingly !
I hope you get it worked out , I'm out of ideas , but I would run another gauge before the filter and one after just to compare pressure drop .
Good luck , Gary
