Walbro 190lph High Pressure Fuel Pump *WARNING - GSS 242* - GSS242G3 FAQ
No — this part has no CARB Executive Order, so it is not for sale or use in California or on vehicles registered there.
Larger injectors or a higher-flow pump change the fuel delivery, so a tune is needed to match them. A direct replacement of stock flow does not.
See What's in the box above. Injectors usually come with new seals and O-rings; pumps with the filter sock or hanger parts the kit calls for.
Fuel work means depressurising the system and working around fuel. Injectors are a careful home job; an in-tank pump takes more time.
When the tune calls for more fuel than the stock pump flows at high load, fuel pressure drops at the top end. Your tuner can tell you.
Sets from the maker are matched within the maker's stated tolerance; the Part details show it when stated.
Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.
Install and care: fuel pumps
Before you start
- Depressurise the fuel system and disconnect the battery before opening a line.

Do
- Fit new seals and O-rings with a little clean oil.
- Check for leaks with the key on before starting the engine.
Don't
