There’s three cents worth of gas in the hose?
As a motorcyclist, this is always on my mind.
My bike takes high octane only. It’s got a small tank, not a 1 gallon or anything that small, but when I do pump gas into the tank - I wind up with the cheap garbage that the guy in front of me pumped. Maybe half a tank of my expensive gas is actually the low stuff.
I’ve found that I need to use gas stations not based on price, but on their use of individual hoses for each grade.
The hose and filter holds 1.3 to 3 gallons of the previous pumper’s fuels.
