Hot springs Grandee minijet leak

[Brad K]

Old Grandee that has a large leak from a minijet, which I have isolated (see pic). As you look at the tub this jet is in the front right corner. The leak is into the compartment area, coming from back right corner which is nearest this jet. I have taken off the escutcheon and added silicon to the orange gasket area. No improvement.

 

I am not too excited about digging through the foam to find the leak. Suggestions? Is there a part that allows me to cap that jet? I have tried a 3/4 schedule 40 PVC cap and it's a little too big. Thanks in advance.

Curious if you were able to solve this and how did you fix?  I have the same problem.  Thanks!
