Fuel pump fittings

Hi. Just a quicky.
Here is my out of tank sytec/walbro competition fuel pump.

Here is a close up of the outlet on the fuel pump, it has a jic -6 fitting..

...a bit like the billet fuel filter i have; that has -6 jic fittings on it too..

..but they unscrew, to leave an internal thread..

Can i not do that to the blue jic fittings on the fuel pump?? Ive given them a quick go but they are tight, as its not new.. So before i get brutal , just thought ide check.

Reason being i need to sort some push on adapters, for the o.e rubber fuel lines.
thanks
