i have everything i need for a d-jet system install on my 914. But i dont know if it fully 100% works. Question is...will the runners for the 1.7 fit my single carb assembly and then run the carb dry....?

Will it work?

It might work, but the chances that there's anything wrong with the FI plenum or TB are pretty small, so you might as well just fit the whole thing. If you're considering switching back and forth easily, remember you'll need to switch fuel pumps to make this work. The carb isn't going to work with the FI fuel pump (way too much pressure), and you'll need to remove the FI fuel pressure regulator to switch back, too. With all that re-plumbing, putting the carb back on is a relatively small thing.

You can bench test a number of the FI components before trying to use them as a system. The MPS usually has problems holding vacuum when it's bad, and that's easy to test. The TPS, fuel pump, and FI distributor are all pretty easy to test. The ECU is hard to test w/o a D-Jet testing setup, but they're rarely bad. The rest is just plumbing.
