My son and I successfully replaced the pump, but it didn't go quite as easily as I'd thought. We could not get the hose that connects the boiler to the pump off. Thankfully, my clever son realized we could turn the portion of the pump that screws into the t-end to get the old pump off and new one on.....tricky, but doable. The new pump is a bit noisier than the last, but she pulls beautiful shots. Thanks so much for this guide!
