Gonna depend on whether or not you get the pony tank installed. I have a Group 31 AGM on the starboard side along with my Noco Genius 10×3 charger, and on the port side I have two 80ah Amped Outdoors Lithium batteries. I do not have the pony tank in there and could very easily fit power pole pumps. I think even with the pony tank, if you do it right you should be able to get the pumps in there. Its just getting in the bilge area to do the work that is tough. A contortionist could have some fun but a middle aged dude who doesn’t stretch often enough will be winded and sore by the time they are done. I fit the latter.
