There are many myths and fabrications floating around out there about gas and water. My father-in-law was a millwright on gold dredges in the 1930s/40s and told me about water injection on gas engines. I played around with it on two of my vehicles and increased my MPGs by 3 MPGs per gallon on each vehicle. The two engines were a straight 6 and a slant 6. No harm was ever done to either motor. I didn't notice any increase in HP, but there could've been some, however slight. Today's engines are all fuel injected, so I haven't messed with the water injection since. Ever noticed how your engine purrs a little better on a heavy foggy day? Both gas and water have to be atomized together before there is a benefit.
Yeah, lotta myths and I know about water injection of aircraft engines. The problem is when the water is in your gas tank and the water is heavier than the gas. It does not mix with the gas and all the water ends up on the bottom of the tank close to where the fuel pickup tube is. The engine might run OK on an injected fuel and water mix in the proper proportions, but it ain't gonna run on pure water, which is you have when enough of it collects in the fuel tank.
Correctamundo Gwolf. The few fuel tanks I've been into did not have pickup tubes that went all the way to the bottom of their tanks. Maybe an inch or so from the very bottom, and some had a screen of sorts on the end of the tube. I've never been to the bottom of a spyder tank, but I'm just guessing that the pick up tube doesn't hit the bottom of that tank. You'd be surprised what lives at the bottom of most fuel tanks. LOL Chunks of dirt, rust, misc debris, and yes, of course, water.
I would not be surprised at what lives at the bottom of fuel tanks. I been working on motorcycles and trucks for 50 or 60 years. Had a lot of fuels tanks off of all kind of vehicles and had to clean them out. Put sealer in some of them. Almost none of the fuel pickups go all the way to the very bottom of the tanks, but they go far enough down to pick up a load of water. It starts out just spitting and sputtering when the fuel level gets low and is sloshing in the tank. If you don't clean it out then, it will leave you on the side of the road somewhere after it burns the fuel out and sucks up a load of pure water. The old Jeep CJ models didn't have but a 12 or a 15 gallon fuel tank. I drained a full tank from a CJ-5 into buckets and had over 5 gallons of just water in the tank. It was probably fueled up at a gas station while the tanker truck was unloading and got a stirred up load from the bottom of the gas station tanks. Most all motorcycles used to have a reserve fuel tank that was nothing but a higher up pickup tube and when it ran out of gas and switched to the reserve, it was picking up in the same fuel tank, but all the way on the bottom of the tank. A lot of them would get a float bowl full of water when they switched to reserve.
