Drum to Disk brake conversion - hose problem

[brap999]

I'm in the middle of converting my front drum brakes on my '63 to Disk brakes. I'm using the calipers off a '79 c10, and have the ECE conversion hoses. The problem I'm having is that the passenger side hose is leaking terribly. It leaks where the hose connects to the caliper. I also bought 4 new crush washers. One of the crush washers (the one that sits between the caliper and the bolt), is not being crushed all the way, so I'm pretty sure thats the cause of the leak. The problem is I don't know how to resolve this issue. I've tightened the bolt as tight as I can, and I'm afraid any tighter I might snap the bolt. I tried using the old crush washer that I got off the '79 c10 as well but it made no difference. The drivers side is not leaking, though I haven't tried bleeding it yet.

Here is a photo of the crush washer: https://i.imgur.com/JWxg4Sv.jpg

Any thoughts, anyone ever encountered this?
