Just got a a 100 gal tank for deisel from tsc and wanting to VENT to relieve pressures. I'm assuming the cap is not vented. Before unloading, removed cap to release A lot of pressure. I know a vented cap can be purchased, but they seem a little pricey. The tank is stored inside of a barn. Can this be vented by drilling small hole in cap, or is this unwise?
The hand pump I'll be using says use on vented tank
