Drilling Holes in Gas Tank...

What is the best way to drill a whole in a gas tank without getting any shavings inside? I am running a return line to an aluminum tank that only has one line going in or coming out... I don't want to have to remove the tank to shake the shavings out... What is the best way to go about doing this?

Thanks everyone,Mark

ive heard that coating your drill bit in vasolene will keep you from dropping chips, its worth a shot??

you can take a shop vac, attach it to the single opening,and set it for it will blow out. just be sure to wear safety glasses.

also, stopping repeatedly to clean it up before you break thru will minimize shavings...
