The relay is accessed through the engine compartment. I don't have a picture but think I can describe it.
Its on the driver side (LHD), top of the inner fender and is about 2/3 of the distance between the grill and the firewall - starting from the grill.
You will see a fist sized hole (cut out) in the inner fender there. In this hole is the relay.
Why Toyota tucked it away like that I have no idea.
To help pin point, look for your ABS unit and you are about the right area. You will likely not see the relay well as its hidden inside the cut out.

Now that I was able to pull the FPR, I could easily stop the FP which allowed me to perform the fuel system service. I posted these pics for those that were interested in ways of doing fuel system treatments on an 80.
This is a pic of the adapter I had made up that allows for a Schrader valve just below the FPR. This was based on a pic provided by others on this board.

This is how the service is done. Basically the FP is shut off, a canister at set pressure forces cleaner into the fuel system. The engine is started and burns the cleaner until the canister is empty.
The important point in doing this service is to measure the fuel system pressure before doing the service. Then set the pressure during the service below the normal system pressure. This ensures that all the cleaner goes into the injectors and not into the fuel tank via the FPR. I measured 30 psi at idle on my rig so I ran my service at around 22 psi.
Why run a fuel system service? I do it to improve my smog numbers. Performance, idle quality, and mileage improvements are all good, but passing the smog test so I can keep my 80 on the road is all that matters to me!
