HOLLEY CHROME CARBURETED FUEL PRESSURE REGULATOR
TWO PORTS, 4.5-9 PSI
This is included with the Super Sunny electric fuel pump
Holley fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. Too much fuel pressure for a given needle and seat assembly can overload the needle and seat and may cause flooding or drivability problems. Each Holley fuel pressure regulator is fully adjustable so regulating the fuel pressure to your engine's needs is a simple task. All Holley regulators are pre-set at the factory so there is no guesswork when first installing the regulator. The Holley 12-803 fuel pressure regulator features 3/8" NPT in/out ports.
Adjustable fuel regulation from 4-1/2 to 9 psi
.220" (7/32") restriction
3/8" NPT ports ( 1 in, 2 out)
Mounting bracket included

Important note from our company president, Skip White
There are a variety of low cost fuel pressure regulators on the market that in many ways appear much like the Holley regulator. These non branded (no-name) products are inferior in many ways, in our opinion. We have sold these products in the past and in recent years, found their quality and reliability to have diminished greatly. The problems included inconsistent fuel pressure, leakage of fuel, poor machining of the housing, and outright failure at a rate we found unacceptable. The main problem is that they fail maintain a steady pressure. The quality control on these no-name regulators nearly non-existent. There are many sources on the market for these low cost products and we have tried many over the years, only to end up with more dissatisfied customers than we care to mention. The Holley and Quick Fuel regulators are fully tested before leaving the factory. There are video clips available on Holley and Quick Fuel's website showing the wet-flow testing procedure. This is not done on just a few regulators out of large batches. It is performed on each and every one of them. The price on the low cost non-branded regulators may be appealing, but quality and reliability are simply not there.
