I can be riding down the road with a full tank of gas and all at once the gas hand falls below empty mark, and the gas warning light comes on. A second later it returns to normal. It will do this continually. Any suggestions?

 

Check the conection on the top of the tank. The only problem with this is you have to drop it and it's not hard because they are poly. Just do it with a empty tank and they are light. One hander no problem.

Why you are in there you can replace the pump/filter/regulator. Auto Zone sells them for like $180 or something. Remember to flush the tank while ya got-r-down.
