I was trying to figure out what is thunping when I apply the brakes at times when I discovered a bigger problem. It looks like by fuel may be leaking a little from the Top Front of tank. Is that where the Lines or the fill go. Anyone else experience this?

 

Fernando,

Yes that is where the fill and the lines to the front are... I am also seeing the same thing... Trying to run my tank empty so I can drop it and see/fix my problem. If you do a search for tipping the box or fuel leak.. you should find some informative treads on this... Keep us posted on what you find..
