Fuel Gauge and Range fluctuation issues
I have been noticing this for a while and thought it may be "normal"
Whenever my car is on a slope, parked or driving on.., my fuel gauge and range display fluctuates..a lot.
If the range display on flat ground shows, for example : 30 miles, when driving on an upward slope, it goes down to 12, 5, sometimes even 0!
Then it takes a bit of time to come back up to 30.
On a downward slope its usually stable and does fluctuate, but only a bit.
I have changed my fuel pump/float unit about a year ago.
