Review on Universal Gas Can Vent Caps Retrofit Kit 3-Pack, Improves Flow for Quicker Refills, Durable Stainless Steel Replacement Vent Valve with Silicone Rubber Cap for Effective Fuel Tank Enhancement by Rip Twin

Tired of the "bull-bull" associated with filling fuel from plastic containers and found this product at Revain. I bought a pack (of 3) to try. Comes with drill and easy to follow instructions. I installed the first air diffuser in less than 2 minutes and it worked great. So I bought 2 more packs of these. Now all 9 of my fuel tanks have this wonderful vent. Now I have nothing to lose by refueling a tractor (diesel) or lawnmower (petrol). And refueling takes less time. I love her!
