DWR550c منظم كربوريتر قابل للتعديل مع تركيبات 3/8 بارب ومقياس

Dialed in my idle mixture perfectly after bolting this on—the gauge makes zero-guess tuning a breeze. Fittings were included and sealed up tight on the first try with no leaks.

Swapped this onto my small block this weekend and the anodized black finish looks sharp against the intake. The pressure gauge made dialing in the fuel delivery effortless, and those 3/8 barb fittings gave a solid leak-free seal with standard rubber hose.

Adjusted the air-fuel mix on my old Holley in about five minutes with this regulator, and the 6AN return line made routing clean and simple. Pressure stayed rock steady even under hard acceleration.
