This fuel valve fits GAZ Series carbureted applications where a UNIKAR-4 style inline valve is specified. It is designed to work with common Soviet/Russian carburetor families and provides reliable fuel shut-off/control to stabilize idle and drivability while protecting the carburetor from debris and backflow.
Why choose this fuel valve?
A fresh valve restores consistent fuel metering to the carburetor, helping prevent flooding, hot-start issues, and fuel odor. The UNIKAR-4 pattern is a proven, serviceable design intended for everyday use in mixed conditions. It’s a straightforward swap during routine fuel-system service and pairs well with a new fuel filter and fresh hoses.
Technical details:
Type: UNIKAR-4 fuel valve for carburetors
Intended carburetors: K-126 / K-127 / K-133; “Weber”-type units (as stated on packaging)
Reference spec: TU 4571-001-50849120-2002
Packaging marking (RU): “Топливный клапан UNIKAR-4 для карбюраторов типа ‘Weber’ автомобилей ВАЗ 2101-2107, 2121, ‘Москвич’ 2141. ТУ 4571-001-50849120-2002. ООО ‘УНИКАР’, Санкт-Петербург.”
Language note: Ukrainian-language marking absent (per packaging text)
Installation note: Inline fitment—observe flow direction arrow and use fresh clamps/hoses
Compatible models:
GAZ Series
Installation tips:
Relieve fuel pressure, clamp the hose on both sides, and catch spills. Match the arrow to the fuel-flow direction. Replace any cracked hoses and ensure no vacuum leaks at the carburetor inlet. After installation, check for leaks with the engine running and re-torque clamps after a short test drive.
When to replace / Why upgrade
Replace if you notice hard hot starts, fuel odor, inconsistent idle, or visible seepage around the old valve. A new valve maintains stable fuel delivery, improves reliability, and helps extend carburetor life.
