I assume this is a typo; your TR2 should have H4, not HS4.

While it certainly wouldn't hurt to try new gaskets, IMO it's more likely
the fitting is damaged.

I don't believe so. O-rings normally need to be captured on both sides as
otherwise they tend to pop out of place when compressed. You might be able
to get them to work by machining a groove into the face of the banjo fitting
or something like that.
But in my limited experience, the fiber actually works quite well, unless
there is some defect in the washers you have (like the wrong
width/thickness/diameter).
You might try assembling the joint without the washers, with the bolt just
finger-tight. Then measure the gap (if any) left by the absence of the
washers, in several places, and compare that to the thickness of the
washers. As I recall, the bolt will bottom in the threads without the
washers, but obviously the remaining gap has to be less than the thickness
of the washers. And of course the gap should be the same width all around,
or else something is distorted. The solution may be as simple as bending
the hard line slightly.
Go ahead and order a couple sets of new gaskets, they are only $2/each and a
good thing to have on hand anyway.
