1. the fuel lines have compression fittings on them, so pull the nut towards the distal ends of the fuel line while hand tightening them to the fuel filter (give it a good tug in both directions after hand tightening).
Not quite - It's an inverted flare, there's no compression ring. But yes, tighten by hand as far as possible. I found that giving the line a wiggle at the same time helps to seat it entirely. Then tighten the nut with a flare nut wrench and a back up wrench on the filter body.
FYI:
Teflon tape is a get-it-home fix. I wouldn't recommend it for anything more. Teflon tape is used to lubricate tapered threads to get the male/female threads into each other tightly. It's the threads that form the seal, not the tape. With any type of flare fitting, the threads don't form the seal. They simply hold the two flare faces tight to each other. You could still get a leak from between the nut and the tube, rather than the nut and the filter.
