Fuel Boost Pump Switch Replacement 337B

[stackj]

I am replacing the fuel boost pump switches in a 1967 337B. As I remember, it looks like I have to disassemble the entire subpanel to replace a simple switch. I will be headed out to the hangar to look over the job in a few minutes and will be checking e-mails and the message board later tonight to see if anyone has had that experience and might have suggestions to save work.

Thanks for any input you may have.

The facia over the switch sub-panel is reasonably flexible. I was able to do the job in less than two hours. That's less than 30 minutes per switch replaced (2 Boost pumps, Regulator selector and Run Stby).

Now if I can just find a Master Sw (S1159-1-1) and a Generator Sw (S1160-2-1) I might also get rid of the fluctuating voltage in the electrical system.
