What Our clients say

“JUST the ticket to fix those miserable ‘gov’t-rules’ fuel cans.”

JUST the ticket to fix those miserable ‘gov’t-rules’ fuel cans. The 1/2″ bit worked best for me. One whack with a rubber mallet and VOILA! Seated!! Just tried out one 5 gallon of diesel in the tractor and it emptied in at least half of the time as before. MUCHO better.

I guess you could call these vents a ‘little yellow gem’. This has to be one of the best products I have bought in quite a while…really! New gas cans now seem to come without a vent so when you pour gas it seems to take forever. Installing this vent is so easy. I was done installing them in 3 cans in under 10 minutes. Now I can fill my generator tank in a quarter of the time it used to.

Items exactly as described. Very easy to install. I especially like the hole on the cap which allowed a string to be attached so I wouldn’t lose this one. The vent was easy to install also. I used a 31/64 drill and tapped the vent in with a hammer.
