Fuel Sender and Unknown Hose
Refitted my newly cleaned fuel tank, and when I went to clean up the sender I realized the brush i was using had Kroil on it which removed much of the brass plating. Should this be a serious issue?
Also, when refitting the tank, I found a hose that runs across the outrigger, then joins with an elbow to a continuous loop that runs up the side back down to another elbow and again down the outrigger. I didn't find it in the workshop manual; the elbow looks like something for a PCV and the hose is about 1/4" in diameter.
Any ideas as to what it is? Is it emission related?
