"Yes you will see a vacuum line going to them."

"them" is not the injectors, it is the Pb sensors it was telling you about.

The auto injectors that I have used and work well are Autoline 16313, low impedence and used in early model Hondas. I would recommend having the original injectors cleaned and flow tested, both sides. Keep all the injector componenets together - Ziploc bags and send to a reputable service.

I have used Witchhunter Performance in Duval WA. He's very good and knowledgeable about the older GW injectors. Answers his phone as well. If you use him send all the parts and pieces with the injector and he will replace as part of the service.
