Despite any opinions of safety it seems that gas tanks are manufactured to not accept more than 95% of their total volume because of regulations. Here is a quote from the US Department of Transportation Federal Motor Carry Safety Administration Regulation 393.67 Subpart E. (12) Overfill restriction. A liquid fuel tank manufactured on or after January 1, ...

There is a kit that contains a new sending unit, float and seal. It retails for 239.20 according to gmpartsdirect.com, they will sell it to you for $124.38. There should be an access panel in the trunk under the mat, so dropping the tank should not be necessary. Expect a shop to bill retail for the part plus an hour of labor. You can probably do this ...

Is it possible that the fact that it rained is a coincidence? Could the fuel just be old? If you leave a two-stroke engine sitting too long with mixed fuel/oil in the tank, the mix will lose some of its lubricating properties---sometimes enough that when you try to start the engine it'll run for a moment, then overheat from lack of lubrication and stop. I ...

You could absorb it with a rag. Either put continue to hold the tank upside down and stick a rag in the collar around the opening or hold onto a corner and lower the rag into the tank. Leave the cap off and whatever residue that is left after you pull out the rag should evaporate quickly.

If you perform the repairs yourself the fuel level sensor seems to cost about $100. When the sending unit goes bad the fuel gauge will usually not move at all. It does sound like it could be an issue with the fuel level sensor in your car. Perhaps the float just needs to be adjusted. Maybe someone bent it out of shape when performing a repair. For ...

It sounds like you just don't know the characteristics of the output of the fuel level sender in the vehicle--perhaps learning more about that sensor would solve your problem. In terms of an alternate solution that does not use the fuel level sender, if the vehicle is a modern one with electronic fuel injection, then it is possible to determine the ...

It is possible to read data from most vehicles' OBD port using a relatively cheap Bluetooth OBD adapter and some client software. Some GPS units have bluetooth, or you could opt for a USB-style OBD plug. This would also allow you to read things like engine load, temperature, rpm, etc. Wikipedia entry OBD Software OBD2 bluetooth adapter

I'd also go with calibrating the existing sensor, but I'd do it the other way around to mac. Start with an empty tank and measure the voltage. add a known volume of fuel, measureagain. repeat until the tank is full. This will give you a series of reference points, and obviously the smaller the volume you add each time, the better the resolution of your ...

Fundamentally, any engine needs spark, compression and fuel in order to run. If it starts when you put starter fluid directly in the engine, that suggests to me it's not getting fuel. If you've already filtered the water out of the fuel we ought to be able to rule that out. The next check is to make sure fuel is actually getting to the engine. How is it ...
