Dear evo users,
Im driving an evo 8 mr, im having this problem when i leave my car for a more than 3 days, i noticed there was some petrol dripping from engine bay area and it happen only when i tried to start the engine. And it only happen when i leave the car for few days, not everyday. So its hard for me to find out the cause. My fuel system mod is only 850 cc injector and fuel regulator. Even workshop couldnt find the problem. Please advise me.

 

It has to be the fuel rail / injectors or the hoses leading to them. I can't think of anything else fuel related.

 

Fuel should have evaporated way before it hits the ground.
