    Posted: 23 May 2014 at 19:54
Got my new to me Norge back home tonight from Cardiff, bike sat outside last night in pouring Welsh rain, first time in two years it has not been in a garage! Started first push of the button next day

Blasted up the motorways, didnt do the scenic route due to weather, big probs keepin it anywhere near the limit, it just wants to go...

Stopped couple of fimes for thr obligatory fuel, gauge started as full and dropped as you would expect. On last leg it was showing half full, i hadnt really been watching it other than the odd glance. Got one mile from home, engine died on me on motorway just before my turn off, pulled in tried starting no go, sloshed boke back and forward, it fired up and ran 100 yards before cutting, did that a couple of times and actually got it to 30 feet fromthe petrol station, put a tenner in - gauge went to half way.

I must admit i stopped using the gauges on the Cali and T5 as they were so innacurate - is a guzzi trend, i mean - gauge showing half when tank empty.

Or is there a common problem with fuel sensor ?

Any ideas

There was a problem with the fuel level on the earlier models. I think they produced a new version of the float inside the tank. But the fault wasthat it never showed full, not that it didn't show empty. Sounds as if you have a sticking float Jim. Not too difficult to remove the fuel pump assembly. Main obstacle is disconnecting the "quick coupler! on the fuel line. Once the tank is free, then undo the 6 bolts round the flange and pull t the pump. While you have it out,make sure you don't have one of those half plastic filters in there. You need an all metal one, Mahle KN145 or the cheaper UFI equivalent (I'll look up the number in the morning). Guzzi do a replacement level float assembly but you might be able to find out why yours is sticking..

Jim, if your fuel guage seems to be stuck,you can take it apart if you are careful, assuming it's the same as on mine.
once the tank is lifted,you can remove the 6 bolts that hold the pump/filter assembly in. There is a rubber sealing washer there, be careful with it and you can use it again.
You will see the fuel guage unit, a white plastic cylinder. Remove the unit and you should be able to feel the float moving up and down. It is held between springs above and below. I recon yours is catching on something. I managed to prise the top off the case and remove the float, check the inside and ease off a couple of moulding flashes. Be very careful to replace the float and supporting springs exactly as they came out, otherwise the guage will never be right again.
But the float unit is now available as a spare, so it might be easier just to replace it. (Originally you had to buy the whole pump/filter/guage unit in one go).
Undoing the "quick release" fuel connection, first of all reduce the fuel pressure in the pipe, unplug the pump electrical connector, then turn on the ignition and try to start the engine. You won't hear the pump run, but turning the engine over will fire the injectors and reduce the fuel pressure in the pipe.
Then get a 12mm open ended spanner, hold it against the connector on the pump side, push the other part of the connector towards it then slowly pull both parts away fron the pump outlet elbow. There is an O ring in the connector and this can be tight, so slowly does it.

in preparation for the worst case - needs new sensor, I spoke to Motomecca to find out price.
 
apparently Guzzi changed the pump for the 8V and it is not possible to buy the level sensor only - new pump at £480 !  if I cant fix it I will just keep using the mile trip to count it out

Is this what they call progress? I know the pump assembly in the large tank Stelvio is different, no doubt the same as now in the 8v Norge.
Still if the assembly is similar, you should be able to take it apart and find out what is hanging it up.

got a tip from Theoneandonly (neil) mgcgb, the float is not a cylinder type,it is like a little railway track that the sensor sweeps, he suggested cleaning the tracks gently and testing out of the tank. Took pump out, it is that type of sensor (metal filter,good) gave it a clean,moved the sweeper up and down, the gauge read correctly, so back into tank, will test it propose on a run to Wales next week.

Actually found it easy to disconnect the fast connector, watched Hayden's video on you tube first

Well, desipte getting pump out and cleaning and testing the sensor it now reads full until about 80 miles in then drops to 3/4 full and stays there ! Back to the drawing board then

I haven't seen one of the new ones. There must be a float in there somewhere and that must be sticking.
 
You tested the guage with it out of the tank and it read correctly, moving from full to empty? If this is the case, then when you put it back in the tank, something is interfering with the movement.

The sensor has a slider that runs up and down the points, there is a float at the end of the arm that holds the slider.

I will look at it again in a couple of weeks as i am about to depart on happy hols

I had the pump out a couple of weeks ago when i broke the connector so it gave me a chance to look at the gauge again.

On third and really close inspection i noticed that the float bracket was actually misaligned and had not been fitted propwely when originally assembled, good old Luigi. I had been looking for a break or obvious fault and hadnt previously noticed the assembly error

It is now working properly and is even nearly accurate - result.

I thought it had to be something like that, good old Luigi as you say.
