It's a 2001 Fiesta Zetec-S, with a de-cat, but does have a MIL illiminator kit on, had a bluefin handset onto the car and got back these two DTC codes.. obviously the reason why my engine management light was on..

P0460 : Fuel Tank Level Indicator Circ Error

Is the first one..

and..

P0171 : Sys too Lean (bank1)

Is the second..

Can anyone help? What the fook is going on, I assume these are related, i.e all to do with fueling?
