The PS-803 is nothing new. Its a professionally modified Holley regulator that's been used for years in NHRA Pro-Stock competition.

Unlike look-alike regulators that make big flow claims yet still utilize the small seat area that froths and foams up the fuel.  We install a 50 percent larger seat area to reduce fuel bowl foam and stabilize the fuel pressure during high flow rates.  You get good clear burnable fuel and more consistent power from run to run.

Once again simplistic design is the key to consistency and reliability. The PS-803 has enough flow capability to CLEANLY feed over 1000 horsepower!
