Multiple tanks hooked up to one valve and hose vs. multiple tanks with their own separate valves and hoses.
Obviously, it’s a different kind of valve in the first setup to prevent backflow into other lines, but that’s probably about the extent of it. With the second setup, you probably need to run a new line and pump for each station for each gas type, compared to just tying the tanks into the one valve and pump per station.
I’m not a plumber or anything, though, so take it with a grain of salt.
There are a few stations near me that have E85, “88 octane” (which is just 12% ethanol), diesel, and three grades of gasoline. Since you can’t mix those other fuels with gas the pump has four hoses and you still have to select the grade of gas.
(US) I’ve been to gas stations in big cities, small towns, little collections of buildings that have no official name but they have a dollar general and a gas station, etc…
I’ve seen several kinds.
Single hose to dispense 87-93 (“normal”) gasoline, and one for diesel
One hose for normal gas, one for diesel, and one for high-ethanol
One for all gasoline types and one for diesel
One super fancy stainless-steel-clad gas station that looked like something from retrofuturism had 5 hoses, one each for 87,90,93, e15, diesel, and the farthest end pump had a line for kerosine.
Here’s a pretty typical american pump: https://www.alamy.com/stock-photo-shell-station-gas-pump-135764267.html
You can select diesel with the green button, which comes out of the green handled hose on the left, but any other option for regular gas (87/89/93 in that picture) comes out of the right hose.
In America drastically different fuels like E85 and Diesel are dispensed with different hoses as mixing those with normal gasoline or vice versa in the wrong system could cause damage. But when it comes to different grades of just gasoline it’s all the same hose. E10 or E15 are pretty much standard in many parts of the Country of Corn (USA) so they are the primary form of gasoline available for normal cars.
Every fuel has its own hose and “pistol”. Each “pump” has two or three or four hoses.
While those do exist in the States too, a single hose and “pistol” is used for all grades of gasoline and the operator presses a button to select their grade of fuel. The only time there is a guaranteed separate is between desil and gasoline:
The button leads to some interesting minor social problems. The expectation is that the use uses their hand or fingers to press the button, but the buttons are usually disgustingly dirty, so that lead many to using the tip of the “pistol” to smack the grade of gasoline which may put a drop or two of gasoline on the button. So those that come next and use their hands end up smelling like gasoline.
No longer interacting with public gas pumps is one minor joy of driving an EV.
i’m gonna be real with you buddy i have never seen a “disgustingly dirty” fuel button so I think the people in your area just grody. no offense to present company.
You never hit up a Shell station? Majority of them and independents I’ve been to have buttons that are worn through on the octane text for low grade. High octane is usually next most worn
I’m in Australia and it’s on the pumps—like little manufacturer stamps that don’t seem to be aftermarket labels. Most people wouldn’t notice it and those that do wouldn’t understand what it means.
It’s generally a tiny label like “Minimum 5L” or something, near the nozzle, or on/below the meters.
I’m in Europe and I have never in my life seen a gas station that dispenses every fuel through just one hose.
Every fuel has its own hose and “pistol”. Each “pump” has two or three or four hoses.
In America, if a corner exists a company will cut it.
It feels like blending hoses would be a more complicated setup?

I feel like we should specific for Europeans or whomever that there is definitely a different hose for Diesel
In the US only diesel gets its own pump, at least in my experience
Same though I do recall seeing pumps with multiple hoses for each grade a lot more frequently back in the '90s and '00s.
Glad someone is thinking of the shareholders
Yeah I always thought so too and then I ran into pumps like this in North Platte, Nebraska last June.

Edit: I couldn’t fuel up at that pump as my car requires 92+ Octane.

Never seen a combined gas and diesel hose though.

I am a refined gentleman who only goes to turkey hill and wawa.
its a thing often in America, there’s just 1 hose and you press a button to select what blend you want.

Not in the us
Frequently in the US.
