Don't forget you can go here, as Tojo noted, the earlier listing works.http://www.toyodiy.com/parts/g_G_1977_T ... MQZGW.html
You can also reverse search if you know the part numberhttp://www.toyodiy.com/parts/p_G_1977_T ... ?hl=48210A
The various bushes are readily available in Australia made in urethane.
I don't have anything on a TE61 with 2TGEU, but if you look here for a TE71 it appears the same general layout. The mushroom shaped thing at the top is not a pressure regulator, it is a pulsation damper which is used to quieten the pump. http://www.toyodiy.com/parts/p_J_1979_T ... _2211.html
My experience with injected Toyota's is with my 4AGE bigport AE86. That doesn't use a pulsation damper at the tank as the pump is intank. The pulsation damper is actually at the fuel rail. I am extremely confident your 2TG fuel pressure regulator will be at the outlet end of the fuel rail.
If you look at the last diagram, you will see the gasket that sit between the inlet banjo and the pulsation damper (23232-26080). These are usually made of copper. Bit of a knock and they will leak. Especially under a car where there is any grit that may get in. I would also be getting the washer 90099-01496. Much cheaper than trying to replace the pump setup, which is probably unavailable anyway. Worse case scenario, you have done $10.
If it really is the pulsation damper and you can't get one, you will probably have to omit it and make up some custom hose.
