There is a very small risk but you have several things in your favor. A
hole saw on aluminum doesn't produce sparks, the aluminum does not get very
hot and diesel has a relatively high flash point. That said I think I would
purge the tank with CO2 or nitrogen first. Also the aluminum chips can
cause a real problem in fuel pumps. .
