I have been running dual 465 for a while, and have had issues with fuel pumps draining the battery when at idle. I have a 200A alternator, but still issues. So I put one pump on a hobbs switch, so both pumps only run when into boost. I do not read of others having issues running two 465s full time, but was curious if other people have run into charging issues. I do not like the hobbs switch, but like the car not starting less.
