Refueling is difficult

[AZ_Ryan]

There's TSB's on it.

The 2nd link shows an actual TSB for the S197. it says the TSB addresses the issue but says it only minimizes the issue. A TSB reflects hard data.

Yet forums talk about having problems filling for the 550/650 ad nauseum. So much that this forum linked to 3 other threads about it.

What are we even arguing here? The people having problems are imagining it? At this point blaming the pumps is only looking at half the argument.

Personal experience. on my 06 GT I had filling click-off issues happen from time to time.....AT THE SAME PUMP I ALWAYS USE.

So the argument is that it's the pump not the car? My argument is some pumps just point out the inherent weak points in the car's fuel filling system. I haven't experienced it yet in my 2025 FWIW.

Anyway, I have 2 new kittens to play with. Brothers I couldn't split up. So here's a palate cleanser.

That TSB is on '05-07 lol. Like I said, we dont need to keep pointing to the 20 year old S197 mustang to validate a problem on a S650. I should also remind you that I never disputed the S197 fueling problems. So that "argument" isnt coming from my end.

As for the S650, I simply disagree with your opinion. If you have real data to back up the saddle tank assertion, then please post. Until then we can agree to disagree. My intention was never to argue. Im sorry you took it that way.

It's all good....no worries.

This is our gas tank. It is commonly referred to as a "Saddle Tank".

It is closer to being 2 tanks with a hump in the middle that gas has to pass across. If there is too much back pressure from filling up too fast, the pump thinks the tank is full before the other side fills up. Some nozzles pump the gas faster than others or are more sensitive to back pressure, resulting in different experiences for everyone.

Literally a Mustang issue for decades.

Class dismissed.

Where does the fuel go?

When I open the fuel filler door and place the nozzle in and start pumping fuel, it goes down a tube of some sort, to where on this picture?
