AFuel Filter
replacement
Here we go then, to
replace the fuel filter on a cinquecento sporting, you will of
course need a new filter, buy this from ebay or your local motor
factor, it would be best to buy two new clips too just in case the
old ones are no good for re-use, knowing a bit about cars in general
I didnt buy a filter specific to the cinq, instead I bought the
cheapest metal bodied fuel injection filter I could find at about
the right size, only cost me £3 including postage £ker ching!!, we
will look at that later.
 |
First off, you need to be able to have good access
underneath the middle of the car, do this via ramps, or jack
the car up, I used two jacks and jacked up one side, now I
fully trust my jacks, and I wasnt going to be pushing or
pulling anything underneath which would potentially make the
car fall on me, however the sensible thing to do would be to
use axle stands and dont go underneath until you are sure
its safe to do so |
 |
Here we have the fuel filter, its on the drivers side of
the tunnel next to the exhaust expansion box, the filter has
two small flexible fuel pipes fitted to it |
 |
Using a 10mm socket, undo the bolt located at the very
top which holds the metal clamp around the filter, this is
fiddly to get to and this is where a good amount of access
underneath really helps, fully remove the bolt Pull the
metal bracket from around the filter, it just bends out of
the way, dont lose the rubber sleeve |
 |
Next, remove the clips holding the flexible fuel pipes
to the filter, you can twist a small screwdriver in them to
break them, you may have jubilee clips, if so then just undo
them, be prepared for the screws to either break, or the
clip to be rusted, pull the pipes off the filter and be
ready for some petrol leakage |
 |
With the filter removed, compare it to the new one, my
"lucky dip" find off ebay was just the same, except slightly
longer on the inlet and outlet pipes, spot on that'll do for
me. |
 |
Fit the new clips to the two rubber fuel pipes, then fit
the filter back to the car noting the fuel flow arrows, the
arrow must point forwards to the front of the car, this is
the direction of the fuel flow, important.
Now wrap the metal bracket round the filter with its rubber
sleeve between the bracket and filter, the next part is
REALLY fiddly, getting the bolt back into the hole - just in
case you want to change the filter again at some point, put
some copper grease on the thread to stop it siezing, when
done, tighten up and adjust the filter position before
making the bolt fully tight |
| All done, it is recommended to run the
engine for a few mins to check for leaks, note that after
startup the engine might stall until the fuel comes through
properly. |

Conclusion
I have owned the car since december 06, and have not previously
changed the fuel filter, in the latter half of 09 I had a rusted
fuel tank, I replaced the tank but still did not replace the filter
[I probably forgot, but there was bound to be rust debris in it],
quite recently the car would stutter slightly under power especially
if the revs were down low, or I changed up too soon, out on the road
for a 15 mile drive after replacing the filter it felt like the
stutter had gone, and overall there was a feeling that the engine
was smoother in its running.
