Injector Adapter for Compression Test on John Deere 750

Please does anyone know what size Injector Adapter I need for my John Deere 750 with a Yanmar 3T80UJ diesel engine?

I was about to buy this kit but It looks like it will not fit. Is there a better kit that you would recommend.

I'm very grateful to all of you for helping me. We were able to get the tractor running well today.

Thank you for filling in the many gaps in my knowledge.
