My does it to, if i brake i gain fuel

It's a known fault with the float in the petrol tank, when your going downhill you'll gain fuel, when going uphill you'll see it decrease.

Yeah fuel sender unit, it's simple to replace, lift the back seat and pull back the carpet so you can see a black circular cap, remove that and it's just right there

Mines same, sometimes i think i've got more fuel than i thought, then get dissapointed

Haha thats exactly what i do! When i get home though i sit in the garage for afew minutes so i see the true level
