Hydraulic Pressure Module Leakage

I was in Kuwait for 2 days trip, after landed and parked infront of VIP terminal in Kuwait Airport, i've noticed hydraulic fluid accumulated below system B hydraulic pressure module, from my observation i suspect it is from System B Hydraulic Electrical Pump pressure transmitter however it cannot be confirmed even with pump turned on , I've cleaned the area and wipe it dry, ready to be verified on next flight.

The next day after flight back to base, confirmed the leakage was from the transmitter base, as per IPC (Illustrated part catalog) there is a seal inbetween. Ordered and replaced the seal, ground check no leak as well on subsequent flight... problem solved...
