Fuel cap.

Hello everyone.

With the original system for filling the gas tank, the French pumps require fuel to run almost drop by drop, to avoid forcing back and stop dispensing.
A refueling then requires a minimum of 15 minutes, and provokes the hostility of people waiting and not understanding why it is as long with a "racing car."

Has anyone here installed it on his GT, a fuel tank cap "quick release" as the original GT 40, for example.
This is what I have on my Cobra, with inside a safety lock with key.
Aesthetics would lose nothing, and functionality would be perfect.
In addition to simple changes in place, it would probably be necessary to neutralize the detection probes of gasoline vapors.

I do not think I have seen that on "racing GT" on or on the black being re built in Germany.

Your opinions and advice of any facility would be precious to me.

Sincerely.

For me a refueling pit stop doesn't take longer than probably 2 minutes (haven't exactly looking on my watch though). Do you think german GTs are different to yours ?

Perhaps you have a malfunctioning filler pipe. Do a search on this Forum for others who have solved a similar problem.

@ BROMBEAR.

Obviously, there is no difference between the GT for France and Germany.
Besides, I bought mine in Germany, (from a totally dishonest merchant with whom I have the worst trouble).
I was referring to the black GT as GT EUROPEAN repairs and transforms more or less track car. I doubt he needs to refuel quickly.

@ HOWARD.

The French garage which has sold most of GT in France, told me he had this type of problem with all the GT and also with the Mustang that matter.
Maybe the the problem comes from petrol pumps in France?

Your idea is good. I will seriously consider the opening of my tank. May be a default ?
Thank you.
 
Saint Ho- In California, our fuel dispensers have a vapor guard that sits back roughly an inch or two behind the nozzle of the fuel dispenser. In order for the pump to go into action, it needs to be snug up against the car, and partially retracted back. At several of the nearby gas stations (the ones with the faster pumps) with the vapor guard engaged, the pump would immediately stop dispensing fuel at higher flow rates. I have this problem with my 911's and it is easily reproducible with my GT's. Interestingly one of my cars (the 05) fills easily while the '06 does not....this could be total coincidence and probably is. The solution for me has been to retract the vapor guard back manually and allow the tank to vent....which eliminates the problem. The downside there is that if the tank fills all the way up and you are unaware, you have little protection against fuel spilling. I stopped filling my GT tank to the gills a while ago, since the fuel sensor would occasionally get stuck on "FULL" for a while and then wake up with the tank half full....at 95% max capacity its never given me a problem....not sure if this is helpful!!
 
@Saint Ho

Sorry to hear that, Hope you get it sorted out.
 
I would be interested in seeing a photo of the filler nozzle on the gas pump in France to see if there is a different design that is causing the issue.
 
I've driven a few GTs in France and never really had an issue filling with fuel - apart from the time we were heading to Le Mans with 10 GTs in the same gas station - that stopped everything....

There are no differences between French pump nozzles and any others in Europe.

I suspect you've got either a very sensitive pump or a problem with the filler neck (though I'd expect the MIL to have come on if the flap had dropped down).

My suggestion would be to have someone check out the filler neck first.
 
I've filled my GT numerous times in France, several times with other GT owners, and I can't remember myself or anyone else ever have a problem with the fuel dispenser taking too long to fill the car. I think you have some other problem specific to your car.
 
Pull half-way trigger on nozzle
 
A big thank you to all for your very interesting and useful answers.

I'll find out where is the fault in my system fuel filler.
It is not very easy to explore the area air.

Love to all.
 
You may also try inserting the fuel handle nozzle in half way. Sometimes if you push it in as far as it will go the auto shut-off gets triggered.
 
I haven't re-read the GT owners' manual lately - well not since 2006 - however it provides a little insight.

Always fill with the lowest possible flow rate to get a full fuel load in the tank.

And never "top it off" when the automatic shuts off the nozzle.

Having filled up my GT more than a few times, generally following the two rules noted, I've found they are in fact "the way to do it".

The variations in fuel flow rates and automatic shut off sensitivity, in the pumps/nozzles, will cause fuel flow to stop prematurely or over filling and spilling.

I have found that early shut off is usually due to the nozzle not pushed in the opening far enough. And has been mention, nozzles with vapor recovery systems, tend to be more troubles. Both with getting a good seal and with insertion depth. For sealing issues the simple solution is to rotate the nozzle with the handle pointed more to the front of the car and insert the nozzle a bit further "in". This method seems to move the 2nd flapper door to make it a bit more open.

I also have found the automatic shut off systems to be very sensitive to not sensitive at all. The overly sensitive ones stop fuel flow well before the tank is full. I found that to be a real pain in the a$$. My method for keeping track is to note the gauge level before I shut off the motor and mentally calculate the number of gallon to fill the tank. i.e. 1/2 a tank is about 8 gallons, 1/4 tank is 12 , low fuel level light is 14-15. And I look at the gallons register on the pump before I remove the nozzle. More than a few times it shut off after 5 gallons or so, and having that educated guess on gallons to full, saved me from leaving the pump with way less fuel than I wanted.

And to address the over-filling/toping-off, fuel spill situation. As many have found out "too full" and you'll have those nasty petrol smells in your cabin for quite a few miles. The inlet of the heating/ac has a seal/barrier from the fuel inlet area. The fumes collect in the wiper area....and this is my best guess ...are drawn out of that area, over the hood and into the air intake for heating/ac system. Due to the base of the windshield being a low pressure area, fumes are "vacuumed" out of the under hood area. Pretty much the same principle as Chevy used on the Cowl Induction System on my '69 z/28 Camaro, but without the flapper door.

Hoping this may help you a bit.

And for those impatient folks behind you in line at the pump, that is their problem not yours. Being sometimes "not too polite" myself, towards those that are annoyed and in a big hurry, I'll open the engine cover/rear hatch and "check the oil level". Adds 4-5 minutes of fun for me and those behind me waiting in-line, pretty sure their blood pressure goes up a few more points.

Exactly what is the capacity of the tank? I'm too lazy to dig up the manual and look...
 
17.X gallons.
 
Thanks B/I!
 
Thank you all for taking the time to help me effectively, and in especially to PLS510*JEFF.
