If the outer bleeds, return the caliper. If not suspect internally collapsed rubber hose.

Remove bleed screw completely. Does fluid flow out the hole? I've seen plugged bleeder screws many times. If so, clean or replace bleeder screw. If not try poking a pick into the hole. Still no fluid? Then perhaps I would return the caliper.

I poked the hole with a needle and now i have not a full stream but a spurt of fluid. Is this going to be enough as i have the bleed hose in a bucket of brake fluid dot 3

A spurt should be fine to get air out
