Will gasoline explode 98 Mercury Sable

Mercury Sable

I am replacing the fuel pump on my sable and wanted to install a maintenance hatch under the back seat. On examination, I noticed fuel lines running in that area, if I accidentally nicked one of those with the grinder is that likely to explode, I am working outside.

Will gasoline explode

No. Gasoline liquid will not explode, however gasoline fumes will. And if there is fuel pressure in the lines the fuel will spray all over and will catch fire.

gasoline combined with air will explode, gasoline won’t burn without air the fumes mixed with air will explode but the gasoline will burn.
