Hence, the other three are still functional, but new injectors seem to hard to find and I have not been able to replace these.   Rebuilt injectors were suggested since the mechanic has access to someone that does the rebuilds.  I would prefer to use new ones, however.  Do you have access to new Bosch injectors, if so, I am interested in obtaining four.   Please advise.  Thanks,  Vic

I want to double what Keith just said. There's no reason to replace 
injectors that don't have some obvious fault. The most common failure 
on these is for the short piece of hose that's crimped on them to 
spring a leak. That hose can be replaced without replacing the 
injector, although most shops won't know how to do this. I do this 
regularly for a quite reasonable fee.

Other than the hoses, these don't "wear out."

Injectors in engines that haven't run in years can rust internally 
and seize up, or the internal O-rings can dry out and leak. Some of 
those can be recovered, but most will need to be replaced.

The end result is that it sounds like the only thing you should be 
concerned about is whether your replaced injector was an original 007 
Bosch or something rebuilt. If you still have your original, it might 
be worthwhile to get its hose replaced and keep it as a spare. To 
keep one as a spare, store it in kerosene, to keep the O-rings from 
drying out. It should keep that way indefinitely.
