Thanks it does not.

I’ve read all the threads.My issue is slightly different. Need help. Low boost sounds sickly weak, it makes a sound and kind of works, but won’t really prime the engine as it did for the entire time I’ve had the plane. This is a change and something is obviously wrong. High boost works great! Strong as ever. That’s what I’m using to start it now. I’ve replaced the low boost switch in the panel but have the same results. I’m reading a lot about the fuel boost pump pressure regulators and have found there’s a replacement regulator kit no. 940150-507 for 28 volt planes with dual alternators. It’s got to be either that or the pump right? Anyone have any experience with this issue?
