19 Pieces Fuel Gas Can Vent Caps 8 Pieces Fuel Gas Tank Vent Caps Replacement Plug with Drill, Wire, Wrench and Warning Stickers(Silver)

This kit is very nice. It comes with a correctly sized drill bit, all the washers,seals and even the wire to fish the valve into the hole from the inside. Installing was very easy. I installed the one in the picture on my water container I travel with. I also plan to add these to my fuel containers...

The construction of the valves was better than expected and the kit had everything needed to put the valve in a plastic gas can that didn’t have a vent.

Works well

A few things to follow when installing.1. Never install the vent below the highest possible fill level of your can when it is sitting flat. This is a non-negotiable safety instruction. WHY: if at anytime down the road of time the valve started leaking it would leak all the gas down to the level of installation.2. Do not drill you hole on the curve of the can. Chances are this would leak. This has nothing to do with the quality of the product. You just can't fit and seal a flat stem on a curved surface.3. When drilling the hole find a flat space above maximum fill level, feed the dill slow and let it drill. This can help reduce the size of the bur that will be left on the inside of the drilled hole. I had to reach in and remove the large bur left by the drill with a pair of tweezers. If the bur is left then it may not seal because the o-ring will be sitting on the bur. There should be an o-ring on the inside and the outside.4. The unit can twist inside the hole when trying to tighten the nut. I used a pair of pliers and a rag to grip the threads while tightening the nut. Don't squeeze to hard or you will not damage the threads. Must be tight enough prevent leaking but not too tight.5. After installation I tested by turning can upside down. Neither one of two cans leaked.

Easy installation. Perfect

Easier to install than expected and everything needed was included. The only issue is that there weren’t any instructions included so some may struggle with it. Here are instructions.1. Choose location for air valve2. Drill hole slowly to not drop debris into gas can3. Straighten out wire included and bend to “c” shape4. wire through drilled hole and pull out through pouring hole5. Remove brass nut and washer and rubber washer from valve.6. Feed wire through valve and bend 1/4 inch to hold into place7. Gently pull wire which will pull valve through hole drilled8. Place rubber washer than brass washer then nut on valve and tighten9. Pull wire firmly to remove from valve

They seem to work as advertised

These looked great in the ad but then they came and I discovered the shiny caps are plastic, not metal. However, they do what they claim. They were fairly easy to install and they don't leak. I installed mine on a blitz 2 gallon plastic tank and the caps don't even screw down far enough to hit the seal at the end, but they still don't leak. Probably because they are plastic and are a tight fit on the threads. Only time will tell if the O rings and plastic caps will hold up to the gasoline. I was a little disappointed but as the title says, you get what you pay for.
