I think the sensor in the fuel filter illuminates a seperate light doesn't it?
Yeah i was hoping it would stop when i put the 12mm pump in and no longer run the #1 Injector link. It cuts out the Aircon and Tacho which sux. Did you replace yours? I am struggling wth the $500 replacement cost but might have to bite the bullet.
