The injectors for my 1hz are the 23600-69055 ones. Seats are 11176-64010.
I've seen pictures of pumps that look different to mine with an extra section on top (called a 'boost compensator'?).
Are there two different versions of the 1hz injector?
What about the injector pumps?
How 'interchangable' are the injector pumps with one another (in terms of their config, part numbers, etc.).
