Finally got a 55 gal drum for diesel, I have an electric pump for it. I assume I'll need to vent the drum when I draw out fuel. I'm thinking of just cracking the plug in the 3/4" bung every time I use it, or is there a better way to provide a vent?
These are not specified for fuel but do work;
for the more frugal of us, get a oil filter with 3/4-14 threads (usually 3/4 bst) and a 3/4 pipe nipple, screw together and you have a good filtered breather
