What model year. I think it is part of the diesel filter housing at least on the euro 4?? https://www.fiatforum.com/threads/ducato-fuel-temp-sensor.422290/
Then euro 4 and is possibly part of the fuel filter housingthe model year is 2008
I had a 2009 3L 160bhp and it was the same filter and housing as the 2.3The model year, 2008, indicates an x250 model. These, were fitted with the UFI "green" filter. My 2006 x244 has a similar but black filter.
The fuel temperature sender, and fuel heater are both incorporated in the filter unit, as is the water in fuel sensor.
Or was the 3.0 litre fitted with a different filter assembly?
sorry lads for not posting the outcome.. here it is, i changed the filter (complete) bought from ebay! it all worked perfect engine management light went off, started and ran the best it has for a long time due to the ecu getting the correct mesages from the sensors, but then the filter split after 100 miles, message to myself DON'T BUY CHEAP FILTERS! Replaced with a UFI filter now running perfect all probs solved no lumpy running or starting, no black over fueling on acceleration. no engine management light. Many thanks to the information received.....Thanks for the replys i will go and chek that
