Help needed - Citroen Picasso - fuel leak or faulty guage

[Evo]

Hi,

Would really appreciate somehelp with a problem on the family bus.

The car is a 1.6 petrol Picasso, it has now repeated the same problem twice. The petrol tank is filled up to the top and the digital fuel guage shows all the bars lit. After 100 miles (as normal) the first bar goes out, then it drops from having two bars out to only half a tank in one hit

The trip reading also shows it only has 200 miles to go till empty, where the hell has all my fuel gone. I can't see it being a leak because the bottom half of the guage drops one bar at a time as normal and if it were a fuel leak it would be the same for the whole tank. I've refilled the fuel tank once it has dropped to halfway and it takes 20 pounds which would equate to 25mpg, the car as it usually does displays 42mpg

This would mean it's not much less economical the the TVR, only i cant get the kids in it for the nursey run

The car was involved in a rear end accident which required the car to be put on a jig, new rear axle etc, could this have damaged the sender in the fuel tank?

Thanks in advance.

Sorry I can't be that much help.. but why don't you just run the tank empty and see how many miles it does? would prove if its a leak or a faulty guage anyway.

I'm going to give this ago, the tank is currently showing 3 bars but still 20o miles on the trip. Looks like it's just the fuel guage not reading correctly, i wonder if filling the tank to the top will reset anything.

I have to be careful running the tank out as my journey is nasty country lanes where it wouldn't be safe to run out. I'll ignore the fuel display and go off the trip, it seems to just affect the top half of the fuel guage.

Could be a faulty fuel tank sender, that's where I would start, as it may just be knackered
