[London808]

And now my fuell wont pump when i cover the exsaust pipe it pumps a bit but never makes it to the engin

[revo_rob_1984]

it could be a couple of things it could be you have a hole in your pressure line that goes from the pipe to your tank or a hole in the fuel line from the tank to the carb or it could be a leak in the tank its self. Id check those they are easy and cheap to replace

whats the best way to check them ?

before going through checking the tank and fuel line. did you put the exhaust gaskets in the header?

best way to check the fuel tank for a leak is get a sink full of water. remove the tank from the rc. with the fuel line still on the tank put the tank underwater with one end of the fuel line in your mouth and the other covered by your thumb. blowing through the fuel line look and listen for what could be air leaking out.
