The 25 amp blade fuse under the hood is the Main FI fuse. #5 is the tank pump.

Any fuse 6—10 is always hot on the left side as a source of +12V to the jumper wire.

+12V to fuse 5 output (right side terminal) tests the Tank pump.

+12V to fuse 5 input goes directly to MAIN pump. Pull fuse 5 to isolate for testing only the Main.
