Normally small pumps like that are self priming but I've also not used them on the resin. Though I know on some lotion bottles, you have to turn the top to get it to "pop up" but I don't think that would be the same for the pumps you're using. What I would do is see if there is a clog in the line. Take it out (wipe off any excess so that it's not making a mess) find a really thin piece of long wire and carefully run it up the tube. If it goes all the way up to the pump part without a problem then if it's still not working then try using that same wire to carefully check the out end of the pump. I've seen liquid soap dispensers get a clog in the pump part and have had luck clearing it out like that. If it still doesn't prime, you might need to change the pump out. I hope this helps.
i had to remove my pump from the thicker material, i think its the A side. its just too viscous to get out with a pump.. i was having to heat up the bottle to get it loose and that sped up the cure time.. so i went back to just pouring it out
Sounds like that might be what you have to do - just pour it instead of the pump. Though using a pump probably would be easier, if it's not coming out easy then that defeats the purpose of having it. A larger pump with a larger tube that is meant to handle larger amounts of material might work too but I'm not exactly sure about how to find a clean unused one to test that idea out.

I use the pumps with both Amazing Clear Cast & the Water Clear resin products. With the Amazing Clear Cast, it helps to warm the bottle in a hot water bath before using to make it easier to pump. Either way I have found the flow to be the same amount. As for priming...just keep pumping to get the product in the pump. I know it's a pain but I prefer using the pumps so much more accurate. It also cuts down on my spills and wasted product.
