I got a comment on my previous vacuum pump video from Ray informing me the Dorman pump I originally purchased is not powerful enough to supplement the brakes in an all electric vehicle. He suggested I checkout the Hella UP30 or UP32. I was not able to find either of these, but I did find a lot of used UP28 which is similar, but slightly lower powered. I purchased one and hooked it up today. The pump reaches the required 10 in Hg in only 4 seconds compared to the Dorman which took 50+ seconds. I won't really know how effective it is until I get it into the car. I also need to hook up the vacuum switch to turn off the UP28 once the vacuum reaches 10 in Hg. This pump is also a lot quieter than the Dorman. There are two rubber grommets intended to buffer the pump from the frame of the car to reduce noise, but they are awkward and will take some extra work to find a feasible way to mount this pump.
