I am working on my bass boat i recently aquired. I am needing to replace the pumps in the boat. I can get to the bilege pump through the back, but cannot get to the livewell pump that sits under the gas tank. I am also wanting to check the lines going to and from the rear livewell that come out under the livewell and behind the fuel cell. Really wanting to clean out the hull really well & rewire pretty much everything. Just wondering how hard it is to do and any pointers on what to do & expect. Thanks.
