I would put the access door under the seat in the storage compartment. I am concerned about being able to reach the pump with it being under the seat. It looks like a long reach to access behind the ice maker.
Yes I know exactly what you are saying, but that then makes the cockpit area no longer sealed. (Like if you left canvas off and it rains, water can get into other areas under that seat). I know someone that did cut that area and now wishes they hadn't. It is a bit more difficult to access thru the ice maker, but it can be done.
