Is it ok to leave power hooked up to the old fuse box and just pull the fuses or has everyone separated out the wiring feeding that fuse box and removed it altogether???

2 - thoughts on mounting the pumps to the engine side of the divider panel. My thought was to attach a short piece of hose to each side of the pump and then use a quick connect (like is used to connect hose to the ballast bags) to connect the hoses together. That way you could simply disconnect them if and when you need to lay that panel down or take it out to access the engine compartment. Doing it this way would make it much easier when it’s necessary to replace an impeller as well
I upgraded my 2007 Supra years ago.

I removed the wires and the small fuse panel it was wired to. That was the only thing routed to those small fuses. I ran all new wire and fuses into a new bus bar. Also new bigger wire from the batteries to the new bus bar. I also used that for new LEDs for the speakers and cup holders.

As for pumps, I was able to mount them over the transmission/back seat area. I mounted them so I could change the green impellers each/every-other year. Another good spot I have seen is on the transom. Some have mounted a piece of Starboard for the pumps above the motor.
