Hydraulic Oil Leak - Need help identifying part
My 98 FDS 36 foot Alpine has had an ongoing hydraulic oil leak(s). I have already had a leaky valve on the parking break and a leaky master cylinder replaced. A new larger leak has now been identified and it is a valve(?) near the rear axle with a black line attached which runs to the front of the coach. Here is a picture of the leaky valve:
Can anyone point me to where I can find a part number for this valve?
Thank you in advance for any assistance.
