[QUOTE="CalBoy101, post: 14224032, member: 154279"] The longest wire run is from the battery to the inertia switch and then to the FPDM. By going from the battery fuse post to a relay close to the FPDM and then to the FPDM you upgrade that long wiring run plus get rid of any voltage drop across the inertia switch. By also upgrading the wiring from the FPDM to the pump hat to the pump you will see some additional improvement but its a shorter wire length so you won't see as much improvement as that longer first wiring run. You should also check both the FPDM connector and the pump connector that's right above the back of the tank for corrosion. My tank connector had some nasty green corrosion on it, I cleaned the male pins with a mini-file and WD40 and used a paper clip to clean out the female pins. [/QUOTE]
