Jonny-Jimbo Posted October 1, 2016 Author Share Posted October 1, 2016 Going back to the fuel pumps behaviour - after the engine has turned off, it has the air percolating up, with a fuel level drop. However, I noticed yesterday evening that when the engine had cooled more, the fuel level rose back up again. Is it normal to get fuel siphoning by itself due to heat?

ferny Posted October 1, 2016 Share Posted October 1, 2016 It's probably turning to vapour from the warmth and condensing back to liquid as it cools. Quote Link to comment Share on other sites More sharing options...
