Vacuum pump mount broke off

[MileHighBox]

Hi all,

Recently I realized that the single-bolt mount for the vacuum pump reservoir broke off and the reservoir has been freely rattling around within the engine compartment. I'm really not sure what to do here, as there isn't an alternate way to mount the reservoir besides that one contact point. See red circles in image below... reservoir and mounting point in the inner circle.

Does anyone have an insight into any way to keep the reservoir secured to some structure within the compartment? Zip tie? Where to? Any insight would be much appreciated!

Thanks in advance.
