First, a Google search does not reveal any existence of a 220. Second, based on what I did find, your pump is most likely one of the many variants of a triplex, self priming, positive displacement pump, as seen in the link. https://www.westmarine.com/buy/shurflo--pump-service-kits-parts--P011_331_003_002
The rubber gets hard or gunk grows on it and then it doesn't seal properly on the forward or reverse stroke. Sometimes in the early stages of failure you may have luck getting it to work as long as it is primed. Wet rubber seals better than dry. If that isn't enough then a disassemble, clean, and reassemble may be enough to get you going in a pinch but complete failure is imminent. The best fix is to determine the correct repair kit and replace the internals.
