Is there a way to find what MX record google DNS has cached?

[Jeff McNabney]

We receive far too much mail at a low priority MX record from google. Must be cached somewhere. Is there a way to determine what records google is using, or to flush the cache somehow to refresh the mx records. If most mail arrives through mx priority 0, gmail is arriving through priority 10.

If you're experiencing delivery issues, you should be reaching out to the GMail product's support channel.  As far as DNS cache flushing goes:

https://developers.devsite.corp.google.com/speed/public-dns/faq#update_cache

And note "these are generally limited to six hours even if the actual TTL is longer".  If you've been experiencing this for more than six hours, it's not a caching issue.
