"MADE IN THE USA" 2-Pack Genuine New Yellow Vent Caps with RETAINING LIP to prevent from popping out of your can. Original Tri-Sure Vents Brand New, Never Used, No Retail Packaging. BEWARE OF FAKE VENTS BEING SOLD WITHOUT RETAINING LIPS - THEY MAY POP OUT OF YOUR CAN. 2 PCS TOTAL Yellow Vent Caps. ASK me if you would like a mixture of other colors Black, Red & White, as some people like to color code their cans. Use Vents for Fuel, Diesel, Kerosene, Gas, Water or anything that you need a smoother faster flow & very easy to install. NOTE: Drill is required to install Vents, you'll need a 1/2" hole at the back of your plastic can above the fill line, then gently pop it in with a rubber mallet. We suggest you drill a smaller hole to start with and then use the 1/2" drill bit. Be sure to drill a straight clean hole, don't swagger side to side with the bit so you won't make a bigger hole than you need. The Vent cap needs to sit in tight to give a good leak proof seal. Helpful Hints Installation card included with every purchase. Gas Cans not included.
