You can just change the cap and without changing the pump or slider. Push the cap down and pull to the left and up. Sometimes you have to wiggle it a little to have it pop out. Detach the tubes from the cap. They are friction fit, so you can just pull them off. If they feel like they are starting to stretch, try twisting them off as to not break the tubes. Make sure the third connection to the cap is covered by the blue stopper (this step is very important). There will be three "holes" under the cap. Two tubes go to the holes that are parallel with each other. The third hole that is slightly offset is the one you need to cover with the blue stopper. Now reverse the procedure to put the new cap in. If you need to order a cap top, try us out at solventinkjet.com. We can help you if you run into trouble as well.
