1980 280zx - loud humming accumulator?

I'm in the middle of a R134 conversion and got the system charged enough to run the compressor but it won't suck in much refrigerant. There is a loud humming coming from the accumulator, I think, which was present before the original R12 system stopped working (and lost all its refrigerant). I think pressure is building up in the accumulator.

Looking around for a replacement - which seems impossible to find (if anyone has one to sell, please let me know) -- but I'm mainly confused about WHY this vehicle has BOTH a receiver dryer AND a low side accumulator. I thought maybe someone kludged it in there at some point but it looks like it's in the FSM.

Does anyone know if there's a drop-in replacement part, or have one of these available?
