So i recently purchased a Ford fusion 2008 and I've had it a week. and i filled up the petrol and the petrol gauge has gone mad literally  off the scale and i have also noticed a missing pipe in the attached picture highlighted in blue does anybody know what its called and how vital is it?.

That is the cold air intake pipe to the aircleaner, without it, you are sucking in warmer air from the engine compartment.  A scrappy is a good place to find one!

Fuel guage, may be a wire off the sender at the tank.

Only two cores from sender to instrument panel... 

I need to correct my spelling - "Gauge" not guage !

 

"fiesta fusion air intake pipe" only gets one useful hit

ok sorry im not at all auto electrically minded so apologies for my stupidity!. what does two ores mean and how easy is this to fix?.

Just two wires (cores from the sender unit) brown and a white.

 The sender is on top of the fuel tank, and getting access to it won't be straight forward. It is possible the sender unit could be faulty, intermittent or bad connection to it or on the instrument cluster itself or even bad wiring between the two.

My guess is the sender connections will be bad, but hey ho it could be any of the above.

Had a read of the manual,( and if it's right ?) the exhaust has to be lowered from the support rubbers to rest on back axle, fuel tank lowered / removed to get access.

Then sender will have to be tested on resistance with a meter, analogue needle meters are better than digital meters for this job - if sender is ok then trace wiring,  again using a meter for continuity from the wiring sender connection points back to the cluster connections.

Years ago for me on mk2 vauxhalls it was always the sender units at fault.

If you aren't confident with this then a visit to an autoelectrician is the call.

58 is fuel gauge sender and e is the fuel gauge

Worth getting the intake pipe added first as the engine running warmer could be causing an issue. Car electronics can be bizarre and often completed unrelated things result in something else appearing to be wrong. On my other car I would get a low tyre pressure warning now and again. Always happened on longer journeys so I put it down to air in the tyre getting hotter and the pressure changing. Nope. One day I started the car, the tyre pressure light came on followed by the engine going into limp home mode. Issue was the the throttle. Car was still under warranty so all fixed at no cost and never had the low tyre pressure warning since.

May be completely wrong but no harm in trying that before pulling bits off the car to try and fix. May also just be the connector needs cleaned or the wire has come out the connector.

thanks for all your advice can anybody tell me the correct part for the air intake my car is 1.4 duratec 2008 fusion petrol

 

is this the correct one?. if so would i need to buy clamps etc and if so which ones?.

I don't think that is the correct part for your car.

Take a look at this Ford parts catalogue: https://ford.7zap.com/en/car/54/code.8c,1.41860,2.5145,6.23941,7.29708,10.32097/14/1550/15380/66843/#9A673

 

See complete part assembly 9A673

There are no clamps.  The concertina hose is push-fit each end and the 90 degree elbow is a twist-lock onto the airbox with 2 small plastic tabs.

It's a pretty poor connection which is why most have fallen off by now!  In reality, it won't make a huge difference to either performance or economy on that engine.

If you still have the elbow and grill mounting, you only need the concertina hose such as this - https://www.ebay.co.uk/itm/Air-Filter-Intake-Hose-For-Ford-C-Max-Fiesta-Fusion-Focus-C-Max-1306950-/185126849556?

As I have this item on both my Fiesta and Fusion, I picked up two from my last visit to a scrappy !

Whilst I’m not suggesting it is a problem on your car not having that bit of hose on there, years ago my brother had an Austin Montego, we did some work on it and then tried starting it before putting everything back on it.  It wouldn’t start.  After much messing about we found it would only start if the cold air intake hose was on there, but wouldn’t start without it.   Very odd. This was in the days of carberretors.

Montego

wasn't that a chocolate biscuit ?

You're getting confused with a "Wagon Wheel" !
