9510 hydro pressure sensor

Last night the sensor for the hydro pressure started leaking or I should say spraying oil. The oil is coming out around the connections so it appears to cracked the sensor. First question is what could of caused this? And I can not find the part on parts advisor so I am sure the dealer will be stumped to.
The sensor is located in a block that also has a small reservoir tank bolted to it. Can anyone help with a part number? I will try to post a pick. I found a plug that fit in place of sensor so I could run but want to get it replaced.
 
Let's try this again

AH 128929 has been replaced by AH224451 $57.43 which requires you replace the plug on the harness with AH228608 $25.24.
 
I went in to local dealer and they said its pretty common and walked back and grabbed sensor and adaptor harness. New sensor seem heaver duty than old one.
 
Just had this happen to our 20 year old 9500. Caught it before it lost lots of oil......................only about a quart and a half.
