The splash guard idea would only be necessary if someone filled the tank to over-capacity (and only even then until you burned off a gallon or so) plus the screw on cap seals the tank and makes it a closed system for emission reasons. Over capacity is, not only filling the tank but also filling the filler tube to the top. Since this is a no-no with modern cars one shouldn't be doing it anyhow. So I am still at a loss to explain that flap...if it is still there on the newest cars and apparantly the 2007 Sonata (at least) doesn't have it. Maybe it is finally being phased out?

Which could be my next vehicle if I swith to a sedan, if it doesn't run well on 87, then I will go with Honda or Toyota.
 
I was responding to someone with a Sante Fe that posted on this forum with 2.7 engine.

But the point that this is not a discussion about the Santa Fe is a valid one, so it would be best to just let that go here, no matter the engine. There should be a Santa Fe Real World MPG discussion where these things could be pursued.

my 04 sonata has a metal flap at the top of the neck ,of the tank .I thought it was to stop gas vapour or fumes escaping before and after filling your car up, why I say this , is because the Flap is on a spring .
91 oct V 95 oct or 87 V 89 Oct
I think for myself it's a waste of money to use higher octane than you need too !
I posted this in March (Hyundai Sonata Real World MPG)page 16 #303
I have put it to the test , Four weeks on 91 oct and four weeks on 95 oct ,got a average 22 mpg 91 oct and the same for the 95 oct , city driving / Trip computer average speed 32 kph / AC on. There was no noticeable different in performance .65 litres per tank 5 cents different in price between91/95 Using 91 for me over a year is a saving $85.00
And I still using 91oct I think the best way to save money on the gas,is in the way we use our right foot.
 
The Test is to try it out for yourself ,using the different Octane and the way you use your right foot.
 
Cheers Jack

#29 of 64 car filling problem by ms090870

I have a 2001 Sonata. The car have been incredible as far as dependability and economics. This car has 97000 miles on it and in the entire time that I have owned the car, the only work that I have had to do to this car is to replace a rear wheel hub. So needless to say I extremely happy with my car and will purchase an other car from Hyundai the next time I purchase a new car.
 
I am currently having a problem with the filling up of the tank. The pump pops like the tank is full but it of course is not.
 
I would appreciate any help you can give me.
 
Thank you

Try another pump. This happens to me on a different make of vehicle once in awhile, but I attribute it to something going on at where I'm getting the gas as it's not consistent. I always noticed the pumps have higher pressure when there are less people fueling up and when the stations tanks are full.
