Well considering this is the forum where people discuss enthusiastically the benefits of adding a second inline fuel filter, or oem filters versus the el cheapo ones from the local dime store, the logic should be clear. Problem is Dr Fauci shied away from making a clear recommendation for two, because he has no control over two of what. Or how worn. I keep seeing the people with one dirty filthy rag worn at half mast. Two of those is not going to do much good.
Fit is, as said in the video, key. You can have a great fuel filter, but if the fuel line is sucking air, the tractor won’t run right.
If you have access to an N95 respirator for work that fits right, use it and cover the exhaust valve with a cloth mask to protect those around you. This works the best for me.
The KN95 masks are easy to get and the material they are made of will protect against the tiny aerosol droplets. I have trouble getting them to fit my face, depends on your face. I like the ones that tie behind your head the best. Stay put.
You guys could figure it out and improvise. I get discouraged about the general population. As mentioned before the problem with common sense is that it is so uncommon.
