DeatschWerks DWR550C Carburetor Fuel Pressure Regulator - 3/8in Barb Fittings

The DWR550c is DeatschWerks' compact bypass regulator for carbureted fuel systems, machined from 6061 aluminum and finished in black anodize. It flows up to 1000 lph and carries four -6AN inlet ports, so a single regulator can feed multiple carburetor lines, plus a -6AN return and a 1/8 in NPT gauge port. The body is ethanol compatible, so it runs on pump gasoline and E85 without swelling seals. This version ships with 3/8 in barb fittings and a pressure gauge already fitted, and DeatschWerks backs it with a limited lifetime warranty.
