ISO carburetor choke breaker diaphragm filter and hoses

Post by Shanemt » Fri Aug 16, 2019 6:05 pm

This like plastic piece broke when I touched it on the back drivers side of the carburetor, and appears to be the choke breaker diaphragm filter. It says aisin 3a27 on it. I’d like to replace the hoses too, but I could also probably reuse them. Any help is much appreciated!

That's a one way check valve I believe. You should be able to replace it with a generic aftermarket one that fits.

I'd replace all of your vacuum lines if your check valve is that brittle...likely the lines are too. You can get a roll of silicone hose on eBay for around $20. Get the 3.5mm...works perfect.
