Heya boys & girls

Hope you all had a great Chrissy & all the best for the new year

Question..........

I am having probs with my fuel guage (MY95). It shows 'full' on refuelling full tank but the needle 'drops too fast' with driving & at 250ks~ it is on empty but then keeps going past empty & eventually runs out of fuel at about 350-390ks~

I have had the fuel sender changed but it didn't fix the prob....

ANY IDEAS GUYS??

Cheers!
Heidi
