That stuff is hell on older small engines. Makes the fuel lines hard, and brittle. I would think by now, manufacturers would have changed them to compatible materials.

Back in the 80's when it came out for awhile, it was eating up the diaphrams on vehicle carbs. You had to buy kits to replace them that used a different material.

Sounds like they were standard Buna diaphragms and they had to switch to Viton or some other compatible material.

Yep, you nailed it.
It would make the buna diaphragms so hard they couldn't flex to do their job.
