John deere 6520 2005 model, the heater plug light keeps coming on to tell me the fuel filters need changing, even after ive changed them! i tried swapping the sender unit on the glass bowl to no avail, it comes on when u let the throttle off and also has developed a flat spot after going flat out then slacken off then full throttle again it sometimes chokes, any ideas?

Sounds like low fuel pressure.The filter sensors come on from low pressure which they think are clogged or dirty.Check the injection pump for air or vacuum leaks,even the feed line is suspect.Check the fuel pump and its lines too.
