Hi - A couple of months ago, I relocated my electric fuel pump to a nearby bulkhead thinking it'd give me easier access for maintenance as well as get it away from heat/vibrations. Today, I was working on the fuel lines and noticed the bottom portion of the filter had some type of discoloration.
Since it's close to the rotating shaft, I thought some saltwater may have been spraying onto it and salt buildup was taking place. Then I noticed there was no such build up on the sticker nor anywhere else on the filter canister. I'm not concerned I may have introduced something that's causing galvanic corrosion. Can someone tell from the pictures what is happening?
For what it's worth, the backing plate is sheet steel that has been painted and there's a ground wire running to the engine block. I appreciate any insights/hunches you can offer to help me understand what's going on and how to address this.
Thanks!
