I was reading an interesting thread here about the V6 Mustang's fuel economy (trip to dallas). The poster memtioned he filled the tank until it clicked off 3 or 4 times. While I'm not 100% sure if it's the case of the new Mustangs, I know this is not good to do with a Ford truck. I also have a 2005 F150, and I did this all the time, trying to get as much fuel into the tank, or rounding off the fillup to an even dollar amount.
I ended up having to replace the charcol canister replaced, as it had fuel in it. It is intended to capture fuel fumes from the tank, but the tech that replaced it said over filling cause the gas to slosh into this canister. It was a couple hundred dollar mistake on my part. The check engine light indicated a code that stated the evap system was faulty. I thought it was the perverbial loose gas cap deal, but after resetting the code twice, it continued to set, and ended up being the canister.

I stop the fueling after the first click now.

 

Same here, after the first click I stop filling,

 

And I normally do too, just couldn't believe it took so little gas to fill it.

 

I don't do that I usally stop after the first click off. Thanks for posting the tip tho. I like stopping at odd amounts so I know I was the one that did the filling up.

 

Interesting point we all try to stop at even numbers 20,40$ per gas trip

 

I always put the nozzle away after the first click unless I'm paying with cash then I'll try to round up to something easier for the cashier.

 

Somehow, i always seem to get the first click at an even $69

 

69.!!! I've never been that high and I'm in Ca with a 500. Explain please

 

I tought my joke was obvious, but let me had this to my original reply.

 

I used to do this, then started paying with a card and forgot all about rounding things up. Sometimes the pump shuts off early on my jeep so I have an idea how much I need. Once I get to that # of gallons, the first shut-off gets it put back.

 

Good info in op, very true. Those canisters on some vehicles can cost as much a $300 plus install and diag.

 

69 is my favorite number

 

I like 73 it's 4 more than 69

 

4 more? Now that seems like it is going to be awkward

 

Thanks for the info! I use to pump to the full dollar amount even if it stopped at 7 cents over. Now I will stop at the first click.

 

You guys are cracking me up.

 

My 5.0 leaks gas out of a drain tube beside the rear tire under the car if I overfill . So I make sure to stop on the first click.

 

That's funny. Mine does that also but only at a certain gas station cause i always top off always have. Never had a problem. I own an F150 and F250. No problems with them either.

 

I always been a one clicker.

 

Hmmmm... I always like to top my tank off, this will be a hard habit to break.
