The gas system reducer/regulator converts high-pressure liquid or compressed gas from the tank into a lower-pressure vapour suitable for injection, part of an LPG/CNG conversion.
If you notice any of the following, the part likely needs replacement:
Engine won’t switch to or run properly on gas
Icing or frost visible on the regulator body
Rough idle or stalling specifically on gas mode
Installation information
Requires professional installation with coolant lines connected (for heating the regulator) and a gas-tightness test by a certified technician.
Frequently asked questions
Converting pressurised gas to vapour absorbs heat rapidly (a physical process), which is why the regulator is usually heated by engine coolant — insufficient coolant flow can let it ice over.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
