When filling up the gas tank it does not fill completely , I was told it could be the filler tank. This car is a 2005 with 18,000 miles, How is this possible since I have been driving cars for 40 years. This is the first car that I ever had a problem with. I purchased it used.

SOURCE: 1998 Mercury mystique v6 "fuel filler downpipe"

Fuel Tank Filler Pipe
The fuel tank filler pipe is of steel construction and is retained to the vehicle by means of two lower retaining bolts and one upper retaining bolt. The fuel tank filler pipe is fitted with a twist-fit filler cap, which seals the system.

I would not replace it unless there was a reason.

Check EBay or if you really want to replace it.

SOURCE: cannot reset on board computer on my 1998 Mercury Tracer 2.0L 4d

Hi Joe, Im not famila with your car as we dont get them over here in NZ, but what i do know is you seem to have your info back to front. To reset your computer in my experience is to disconnect the negative terminal and press on the brake pedal and hold a few times to drain the power from your computer (ECU) or leave off overnight (which wouldve been the case when the car sat for a month) I think what your mechanic means is to re-tune your ecu by letting it re-learn after a drive but i dont know what the hundred miles is about?? your computer should tune itself faster than that! Driving that far would be about how long a computer takes to adjust itself after a tune up or higher quality gas "without" reseting your computer.You computer will instantley ****** the timing if knock or lean mixture is detected to protect the engine but is very slow to advance it (hence the long drive). I suspect there is still a wee electrical problem thats why the computer reads "status not ready). The only advise i can give you from here is a auto sparky is more likley to find the fault than a mechanic!
I know i havnt solved your problem as it will be a hands on elimination process but i hope i have cleared up a few confusing things that you have been told.

No, thats not true. Theres no real difference in fuel octane.Sounds like you have a leak at the gas tank some where or the fill tube from the gas cap to the tank is crack , loose or not on right..Hope this helps you and have a great day....

Diagnose gas tank fill problem

The vent in the filler neck is more than likely sticking. That is if you are having trouble filling the tank up, or if it fills too slow. Also is there a check engine light on? Try and describe the problem when filling tank. ie: tank fills slowly, cannot fill tank, gas splashes back when filling.

How many miles per gallon does my pontiac get?

Fill the gas tank till the filler nozzle clicks

Zero the trip meter

Drive the car for say 100 miles

Fill up the tank again until the nozzle goes click again

Take a note of the number of gallons you put in divide that number into 100

So 5 gallons divided into 100 will tell you that the car is doing 20 mpg

if you have added 4 Gallons and 3 pints then divide the 100 by 4.40 which gives you 22.73mpg

Gas tank filler hose on Ford E Super Duty Motor Home

Look again into the fuel filler there should be a metal hose which is where the tank gets it's air from, ensure when your filling up your not pushing the fuel filler gun fully home when filling up, suggest you don't fill the tank right up to the very top as your correct it's a big job & you will need parts before you take the tank off.
