RE: RS4 18ss and EVO: PROBLEM REPORTS (Official thread)
First design flaw of a stock rs4 is the fuel lines so close to the gears! Alot of people have chopped their fuel lines due to this.
Solutions :1) Get longer fuel lines and re-route it.
2) Get a racing fuel tank.
3) Blutac it onto the 2speed cover
4) Turn the stock tank the other way around (you can only put fuel when the shell is off and need longer fuel lines)
