Re: Fuel Injector Question

[Brett Dikeman <brett@pdikeman.ne.mediaone.net>]

The older CIS injectors had a design which put the rubber seal very close
to the engine and hence it could overheat.  The injector cooling fan
completely compensated for this, I believe...and Bosch redesigned the EFI
injectors to use the new design(but didn't bother with the CIS injectors,
I think.)

Our injectors should be fine..these changes were all made in the early
80's.
