Not my idea. I would like to give credit but I cannot find the post where it was mentioned.
I purchased 2 feet of 1/2 inch plastic tubing from Ace hardware.
Remove the cap and O ring from the cart. Attach the cart to the tube and place in hot water. Suck on the end of the tube and bring the water up about 3/4's of the way. Blow the water out....repeat....repeat....I alternate between both ends of cart.
I have been refilling without drying and seems to be almost perfect. Drying should make it perfect.
Good luck...
