I have installed them in many of our customers cars and have had no failures to speak of. I have called Walbro and they told me that the pump had no issues with the voltage. Plus when I was running out of fuel on my GN at the big end, I installed a Boost a pump and was able to keep the fuel pressure stable and did not need to install a second pump. I like mine and feel it was a good choice instead of installing a second pump that I only need 3% of the time I drive it.
