>Tubing coupled to a barbed fitting is secured by a hose clamp. You could remove the clamp and then the tubing.
What is the chances that barbed fitting is a separate part and is screwed onto the discharge outlet?
Is it possible the discharge outlet is threaded.. And that visible barbed fitting was screwed onto it?

If the discharge outlet was barbed, then why are there those 2 bits sticking out? what purpose would they serve to the discharge hose being clamped onto the barbed section?

This pump comes with accessories, like circlips and inlet hose filter.. does this help identify what's going on?
