Hobbs Switch?Wild1 07-05-2003, 01:53 PM Newbie to N2O, what is a Hobbs Switch? I can understand how it would work with a turbo or S/C but I can't figure out how to use it with N2O. Any benefit? Is it something like a window switch? Or a Fuel Pressure Safety Switch? slow 07-05-2003, 03:08 PM the fpss is a hobbs switch. Ryan. Z28ROC 07-05-2003, 04:29 PM Fuel pressure safety switch. It will shut the n2o off, if the fuel pressure drops below the set psi. Wild1 07-05-2003, 04:44 PM So is it adjustable or is it set? If I'm running a separate tank (low psi) for racing fuel (3 gallons) up front where the battery used to be, then how would I adjust the Hobbs/fpss?

Hook it up to a air compressor to get the psi u want. Wild1 07-07-2003, 07:24 PM Air Compressor... great idea. | ||
