RV12... Diesel?
I have a bit over 135h on my RV12, and did my annual about 4 month ago without much to report on.
Last week I was caught in a serious rain, so with a wet plane, I decided to spend the afternoon cleaning, making her look shinny again.
Once under, I noticed that the inspection cover that goes just below the gas connections in the tank, was yellowish, so I decided to remove it… …and voila! There was an oily film around it, which was forming from a drop coming from the fuel return line.
I cleaned the whole think with a solvent, tightened a bit more the nut (about 1/6 of turn) and have been monitoring it for the last 5 hours.
The good news: Nothing more has come down (yet).
The bad ones? What do I have in my tank that mixing with the micro-filtered premium gas yields such an oily substance??
Any guess is appreciated!
