These fuel Vent Screens will keep the bugs out!

We all know that the fuel vents on our Grumman AA-1 & AA-5 aircraft can be very attractive to mud daubers, hornets, wasps and other insects looking for a place to call home.

We also know that these critters can plug  the fuel vents on our Grummans overnight. They usually build their homes some distance into the vent and where they can be easily missed during the preflight. Don’t experience  the fear of looking out to see your wing deforming.

Fresh Aero Bug Blockers for Grumman AA-1 & 5 series aircraft that will prevent these troublemakers from sealing your fuel vents and maybe your fate.

Features Include –

  • Formed from stainless steel wire screen  for excellent durability and corrosion resistance.
  • They easily slide over your external fuel vent tube for a perfect fit.
  • Open mesh screens will block bugs but not the air flow.
  • The integrated “O” rings molded into screens provide a tight compression fit. They will stay put.
  • Very easy to install. Just clean the end of your vent tubes and push the Bug Blockers over the end of tubes.

Installing Your Bug Blockers

1. Confirm that your fuel vents are clear. One option is to use a length of safety wire or a pipe cleaner with a small hook on one end. Push the hook into the vent about 3 inches and twist wire while pulling it out of the vent. Repeat this procedure several times to confirm that the vents are clean.

2. Use a “Q-tip” to clean the end of the vent tubes with a non-oil based solvent.

3. Slide the Bug Blockers over the end of the vent tubes. 4. The Bug Blockers should fit snuggly. If they fit loosely, remove them and use a Q-tip to apply RTV adhesive/sealant to the exterior of the vent tubes, slide on the bug blockers and allow the RTV to cure for 24 hours.

WARNING: do not apply RTV the inside of the tube. If this happens, be sure to remove the RTV before proceeding.

5. Enjoy the peace of mind that the Bug Blockers provide when flying your Grumman.

Keep in mind that using the Bug Blockers does not eliminate the need to inspect your fuel vents when performing your pre-flight inspection.

The vents still need to be checked. However, it certainly makes the job easier as you just need to inspect the surface of the screen for any blockage. Be sure to inspect for screen looseness too.

Another important warning on back Fresh Aero Bug Blockers Fuel Vent Screens for Grumman AA-1 & AA-5 Series Aircraft The Steelebrook Group WARNING!! Another Important Warning A few customers have asked if the Bug Blockers are more susceptible to icing than the open fuel vent tubes on the Grummans. We have sprayed a continued mist of 50 degree water at Bug Blockers on a test stand in sub freezing temperatures with no buildup of ice.

Also, in the many years we’ve been making and selling these fuel vent screens, we have not received any reports of icing issues.

That said, we’ll continue to sell the Bug Blockers, but we need to limit their use to warm weather flying where there is not even a remote chance of icing conditions.

So, if you use Bug Blockers on your Grumman, remove them in the winter (not many bugs in the winter) or if you’re planning to fly where icing may occur. Sorry for any inconvenience this may cause you but the Bug Blockers are easy to install and remove.

And we do need to err on the side of safety.

If you would prefer to return your Bug blockers to us rather than removing them when icing is possible, we understand and will certainly return your payment.
