Details
This UPGR8 fuel pressure regulator direct bolts on the stock Honda or the aftermarket high volume fuel rail. Because it is tapped to 9/16- 9/18 threads, the fuel outlet port allows various different hoses ranging from stock Honda fuel return hose to -8 AN hose.
The vacuum reference is at a 1 : 1 ratio. For every pound of boost on turbocharged or supercharged application results in a 1-pound rise in fuel pressure. You can adjust from a range of 30 PSI to the maximum the fuel pump can deliver.
