KB Boost A Pump
I looked but maybe not hard enough. How do you know if this is working right? And if it isn't will it cause any issues with fuel other then it not working. Not sure if that makes sense. I guess I mean will it just be a paper weight or cause other issues while connected.

Is your car supercharged? if the KB boost a pump is not working right you could be starving your engine and could start melting pistons or cause detention, you need a fuel pressure gauge to verify constant fuel pressure through out the RPM range.

Yeah it is but also has an a&a secondary fuel pump. It's running rich so I think it's ok fuel wise my pressure does fluctuate when below the secondary cut on. But once it cuts on its solid 62 psi. I been trying to find the fuel pressure fluctuations not in boost. Was wondering if the boost a pump failed would it cause voltage issues to the pump.

Throw a multimeter on the fuel pump wire harness and ground the bap switch and you should see 17v. Easy and you will know for sure if it's working. I would rather know then then to "think" it's ok especially with fuel..
