does gasoline caramelize or something funky like that when it sits in the sun for a while.
I have a glass filter before my fuel pump and I originally thought I was getting oil in the fuel somehow because after it sits for a week or two there is a little puddle in that glass bowl. The gas is all dark and thick, like it has oil in it.
The thing is, I changed my fuel pump because I thought that was the culprit. But I have the same thing still. It's only after a good while that the gas in there gets like that. My car is oriented so the engine faces the garage door and the windows let direct sunlight come right on it for part of the day.
Is there still oil getting in there or is this some reaction that gas goes through?
