Damn, they must've just went back to this. I replaced the head on my HPFP about 2yrs ago. It was definitely a pain trying to hunt one down. Due to all the shortage everyone was experiencing then, you had to get on a list at some places just to be in the manufacturing line to get one. Other dealers weren't selling their stock in the event they needed them for their own repairs.

- Yeaaaa, it was obtainable, but a real pain to get one. I ended up with a reman as it was all that was available.

I would've thought that mess would be cleared up by now. Sucks if not since there is a major difference in price between a head assembly and an entire pump.
