NEW PROBLEM PLEASE HELP, i installed the new sending unit,i then started it up but i cut it off to check under the car for fuel leaks and i found 1,its comming from the fuel line where it connects to the sending unit tube, i noticed when i was taking off the fuel lines when i was using the fuel line tool the little clip thats sits in the tube popped out and got bent,i had put it back in the line but didnt look like it was sitting in there tight like the other clip that was in the other line, do they sell those metal clips???? they was some plastic ones on the sending unit when i bought it but dont know if they work??? any help please
