You don't need a regulator with that low pressure pump. The stock VRO pump will spike upwards of 9 PSI or so if you put a guage on one. One big word of caution is to watch your voltmeter. The 140 looper has a WEAK charging system to say the least. Mine only put out .3-.6 amps at an idle, and didn't ever reach 9 amps(rated output) until 6100RPM's(redline). At a 3800 RPM cruise it only put out 3.6-5.1 amps, so it never really kept up with many accesories, and I always had to put a charger on it when I got home. The early 9 amp charging systems were pretty sub par to say the least.
