Fuel gauge suddenly drops,comes back, then drops again?
Discussion
Hi,
Last week I jumped into my car and was unable to get it going. I managed to jump start it and drive off with the alarm going on and off. At the same time my fuel gauge was fluctuating. Then after about half an hour the alarm stopped and the gauge settled. I'm surprised the battery went flat so quickly, as the battery is new and I thought it had been used about two weeks ago.I took her for a run today and she fired up ok,but later the fuel gauge suddenly dropped again. Any ideas?
Thanks Mark

.... Lots of info on changing the sensor on this forum Not a bad job and cheap but can be a pain to get it all to seal again.
EG http://www.pistonheads.com/gassing/topic.asp?h=0&a...If you do change the sender but re-use the original float it's a good idea to check to see if it still air-tight. I thought mine was OK but since it went back in the gauge shows empty even though there are still about 5 gals still in the tank. I suspect the float has a pin hole in it and has leaked some fuel making it heavier, so it now sits below the surface of the petrol.
