Yup, I did it on an OS120 surpass.The pump went bad. Sat without covering the nipples for 5 years and that ruined the pump. I plugged all the nipples and used a Perry Oscillating pump. about 25 bucks these days. I use that pump on any model where fuel tank position is in question.

If you download the instructions you will also see the recommendations for storage. I didn't and it sat for years and never worked again. I tried all the suggestions and the pump just didn't work. Perry solved the problem
