Poly holding tank pipe thread seal

Hi Gurus

I'm replacing the holding tank (old one was a "bag" type) with a new Todd Enterprises Poly tank from West Marine.
The 1.5" pump-out and inlet hose fittings do not "tighten" - the pipe fittings have no flange on them and I could probably screw the fitting right through into the tank if I wanted to - albeit with a pair of gas pliers. They are "tight" but I don't think they are "sealed" - I May fill the tank with water and food colouring to check for leaks, but then I may not be able to return the tank if I have to

One idea is to try and install the tank so that all the hose fittings are at the top of the tank (with a pick up extension hose for the pumpout) but I'm still worried about leaks when the boat is heeling and gas/odor escaping

Should I Teflon tape them, Glue/epoxy (won't stick my guess) - any other suggestions?

Is this typical for Poly tanks or do I just have a bad one?

Regards and thanks to all who take the time to respond

Tom
