I had an 98 Chevy that would "run not run" for about a month. I finally pulled the tank to replace the fuel pump. One of the leads was completely burned in two. The end of the wire was black and burnt and there was melted black burnt plastic on the pump. I Never drive a vehicle below a 1/4 tank which means this burning took place while submerged. If it had been empty would I have been speaking to JESUS?
An important point I want to make ( been said here but not clearly). Liquid gasoline does not burn, what you see burning is the vapor part as the gasoline vaporizes. The vapor mixes with the oxygen in order to support combustion. There is no oxygen in the liquid itself. Once the vapor is lit it may appear that the liquid is burning but in reality what is happening is the heat from the reaction is causing a much faster vaporization of the fuel and therefore a bigger fire. The reason the container must be full for the match to fail to light it is because it gives the vapor nowhere to collect. But if its warm enough outside when you do this, enough vapor will be forming off the top to light it anyway. So PLEASE don't burn your head off PEOPLE!!!!!!!!
The idea that there is no oxygen present in a fuel tank is false. We all should know by now that a tank will draw air in through the vented cap as we burn fuel driving. Anybody who has every had a bad vent on a fuel cap (older vehicles) knows that familar "sucking sound" as you take the cap off. And those vapors will burn in a low oxygen enviroment ( they just won't explode).
So I say YES denny I agree with you, if for some reason you had a spark inside a tank with a low level of gas there would be some statistical chance. I also know how sending units work they read resistance difference between a known ground and the one on the unit at a millivolt level. ( try and make one spark I bet you can't )
OK I'll shut up now.
P.S. Anybody know a good site to buy a frame tank kit from. For some reason I am very leary off my cab tank now. LOL
