Walbro fuel pump kit for 02-07 WRX/ 04-07 STi - 400-791 FAQ
It is listed for: 2002-2007 Subaru Impreza; 2004-2007 Subaru Impreza; 2006-2007 Subaru Impreza and more (see the full list above). Pick your vehicle on this page to check your exact year and trim.
No — this part has no CARB Executive Order, so it is not for sale or use in California or on vehicles registered there.
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
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.
- Work outdoors or in a well-ventilated space, away from anything that sparks.
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
- Don't run larger injectors or a bigger pump without a tune to match.
- Don't reuse old seals.
