Holley fuel fittings

I just put a new Holley dual feed carb
on my 383 in the cuda. I bought a Jegs
fuel line 555-100824 and installed it.

The problem is the fittings are as tight as I
can get them and fuel is spaying past the gaskets
on the fittings at the carb inlets.
Question is, according to Jegs instructions
teflon tape or sealer should be put on all
fittings, Has anyone done this?
I have always had the gaskets only and not
had a problem.
The fuel pressure is 6 psi and the floats are
set with fuel just at the bottom of the sight
plugs.
thanks,
