Fuel gauge erratic

The fuel gauge is not dependable. Even if the tank is full, if I let the engine for 2-3 minuets the gauge drops to empty and the alarm sounds. Is there an easy access to sending unit in the gas tank?

Thank you, Dominic

Hello,

There is a tap door for the fuel pump and fuel sender. Here is a guide that will show you what you are in for when doing the job. Yours will be easier because of the access hole.
