Emissions Pump Filter Mod

Anyone know if the foam filter itself is something we can buy?

I’d probably prefer to buy a replacement once in a very blue moon over bolting on a whole ‘nother filter.

 

Not trying to be negative here, but even if you could buy another filter, why?
Replacing the weak item for a replacement weak item. Delete it a put a filter on that can’t be sucked into system, causing more issues.

 

For some reason a filter replacement isn’t sold by Toyota

 

Since failure is still so rare, I’m figuring it’d be nice to stick with the existing design.

There’s also the question of whether a metal mesh could effectively solve this worry (or at least buy a lot more time) since that just occurred to me.

I found a comment in there claiming the mod took out his pump months later but of course take with a grain of salt.

Darn, thanks!

 

I did this mod very early on in my ownership. For me, I was concerned that in AZ, everything plastic, rubber, or foam has a potential to disintegrate without warning. My truck was already at about 4 1/2 years when I got it. As it turned out, the existing foam was in good shape but I went ahead anyways. As was just mentioned, the foam is not available separately so this seemed a good solution for me. In the end it probably doesn't matter one way or the other if you do this mod or not. I'm happy to have it done in my case.
