Our FASS 150/180-1010@45PSI kit is a good one for the 12V. We have had lots of positive feed back from some pulling customers and such. And now with our loud pump fix, these pumps are more manageable in the noise department. (Some not any louder than a 150 GPH pump) AND if you wanted to run a boost reference regulator, you can get a weak spring for the regulator in the FASS (To pull the FASS pressure down to about 10ish) and install the regulator on the FASS return line going back to the tank and set it to what pressure you want. . This will net you similar results if you wish to do so. I think David Lott is doing this with some of our Ford kits…. and those are not much of a stretch from the 12V 1010 kits.
