|  Fuel Remaining in Gas Pump Hoses
On average how much fuel is trapped within the gasoline pump hose ? Here is why I ask: On the way to the track today, after I got off the freeway (about 35 miles from home), I filled up my bike before entering the track. The problem is that I only put in about 0.9 gallons of gasoline. So I started to think, what happens if there is more than 0.9 gallons of gasoline trapped in the hose and if the person using that same hose ahead of me was pumping 87-octane gasolines, then I just pumped 0.9 gallons of 87-octane gas into the tank of my gixxer which specifies 90-min octane !!! In this case,that wasn't much of a problem because I left home with a full tank of 109-octane race fuel, so in the worst case, I get about 104-octane average. However, for my normal canyon runs, I use 91-octane (the highest we can get at most places in California), so if I mix 0.9 gallons of 87-octane gas with 3.6 gallons of 91 gasoline, that averages out to only 90.2-octane, barely meeting the minimum requirement. This means that I gotta plan my fueling carefully and stop doing these 1-gallon fill-ups so that I don't keep pumping 87-octane gas into my tank. Is there anyone who would know how much fuel is trapped in the gas pump hose ? Thanks in advance. |
