Wiring in a KB Boost a pump - Page 5 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

We wired one after the FPCM about 8 months ago. No problems at all. Fuel pressure would drop to 38psi at high rpm before. Only dropped 3-4psi after the BOP/It was boost activated. I wouldn't leave this thing running at a higher voltage all the time.I don't think it's made for that.

Ok I followed the KB instructions and the LF instructions. kB is vague and LF says go to step 48 yet the instructions stop at 47. So. Where the hell do I hook the boost switch that I ran from the back to the front of the car? What line do I tap into? Please please help. Anything will help. Wiring is done. No issues. Just trying to figure out the boost switch with the fitting at the front. Where do I tap into?

its a boost switch, so you need manifold pressure/vacuum. Tap it into the large vacuum line that runs from the back of the intake manifold over to the brake booster.

btw, this post is almost 10 years old.
