FamilyGuy Posted July 7, 2014 Share Posted July 7, 2014 Having an ongoing problem with air getting into the fuel in my Focus 1.6Tdci. First thing that happened was the car just cut out and diagnostics suggested a fuel rail pressure sensor so that was replaced. Then, following a full service, the car would just cut out every 500 miles or so. Our local garage has changed the sender unit in the tank, pressurised the fuel lines and changed all the seals but the problem still exists. When the car is running it is perfect but I need to get this sorted. It appears that the air builds up in the filter unit until it goes unto the pump then cuts out. Has anybody else had a similar problem? Can anybody help.........please Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 8, 2014 Share Posted July 8, 2014 Has anybody checked the fuel filter or its housing? Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted July 8, 2014 Share Posted July 8, 2014 +1. Also is the filter seal new and/or fitted correctly? Sent from my S5 Quote Link to comment Share on other sites More sharing options...
FamilyGuy Posted July 8, 2014 Author Share Posted July 8, 2014 Thanks for the reply - had 2 new fuel filters fitted - both the full Ford units with no joy. Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted July 8, 2014 Share Posted July 8, 2014 But did they also change the seal? Ford kits don't always come with one Sent from my S5 Quote Link to comment Share on other sites More sharing options...
FamilyGuy Posted July 8, 2014 Author Share Posted July 8, 2014 Its a sealed unit with 2 pipe connections and a electronic plug. been replaced twice in case that was faulty Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 8, 2014 Share Posted July 8, 2014 the only way to get air into the fuel system is with a leak in the fuel system, so this is most often as described - the fuel filter / bad seal. Alternatively it could be the fuel pump is drawing air into the system. Are you able to provide a definitive list of all that they have done to look at this issue?

Stoney871 Posted February 11, 2017 Share Posted February 11, 2017 Was the filter seal changed as well?It is always recommended to do the filter and seal at the same time.Sent from my SM-G930F Quote Link to comment Share on other sites More sharing options...
Patrick Pearson Posted January 18, 2023 Share Posted January 18, 2023 Hi had anyone found a solution to this issue I have this at the moment and my mechanic has no clue where to start. The only thing I can add is that it seems to happen soon after I refuel. Quote Link to comment Share on other sites More sharing options...

Firstly you need a mechanic that knows and understands diesel engines. Have a look online in your area for a 'diesel fitter' When was the fuel filter last changed ? If it is more than 3 years old then replace it as a matter of course. Quote Link to comment Share on other sites More sharing options...

Patrick Pearson Posted April 23, 2023 Share Posted April 23, 2023 Hi my mechanic has sorted it. It was the mass air flow sensor. Quote Link to comment Share on other sites More sharing options...
