ok so just a replacement of the pump does not require timing, Im going to order my stuff and tackle this beast as soon as it gets in. I'm guessing it will be better to buy the new injectors fora little more money than the refurbs right?
If you can afford the time, I would get the injectors from Russ (typ4 on here)...from him, you'll get a set of new injectors that will be matched to the same pop pressure.
And, there's no way to replace the injector pump without re-setting the timing...you could make a mark on the housing and clock the new pump there, but because of subtle differences internal to the pump (particularly since your old pump's worn), you won't have the timing dead-on. There's a mark on the housing already, but that's meant for you to align the IP and have it in a position where the engine can be started, so that you can check the pump timing and set it properly.
Replacing the pump isn't THAT miserable of a job, although it'll be a bit more difficult in a van chassis. If you can find a fellow board member with the pump timing tools, or find a shop that can set the timing for you, you can do the swap yourself...FWIW you shouldn't run the engine long-term with the timing set incorrectly, but you can drive it at least to a shop...
