Comes with everything you need and install is about an hour. Happy with product so far on my E85 wrx.

Great Product

I installed this on my 04 Sti, hardest part was getting everything out of the tank. One way out and one way back in hahah. Easy plug and play if you wanted to go that route. I would suggest taking the In tank fuel filter out and run a fuel line strait up and then put a In Line fuel filter in you engine bay. My stock in tank fuel filter was leaking from the factory and cause bad number on dyno.

Works good with my 2005 sti. Took some work, but not bad at all. Just bending the tabs on the fuel pump mount. Be careful with the wiring harness. Mine was too short, and the wiring was backwards so it didn't pump gas. I used the old one, and it worked. Tried it three times. Still a good product so far.

Great upgrade for Walbro
Rebs 1 year ago
Bought this to upgrade my Walbro 255 Lph FP. Walbro was nice but a little bit noisy. This one is relatively quiet. I had a professional mechanic do the install and he remarks that it was not the easiest install he has done.

I recommend installing this fuel pump if you have upgraded you turbo. Easy install, just plug it in and it's done.


  • AnswerQ: 565cc injectors   j_gonz145356 22 days ago

    Can I use some stock sti 565cc injectors and this pump with e85? If not how many cc's do I need the injectors need to be so i can go e85

    • A: You can use this pump with the stock injectors and E85, but 565cc injectors will limit you to about 290whp on E85. Please contact customer service for recommendations on injector sizing.

  • AnswerQ: Will it work  arogacgenko 4 months ago

    Will it work in a 2013 wrx?

    • A: As per the application list this is not confirmed for your vehicle. You can get the universal install kit, then use pig tails to hard wire it in your WRX.

  • AnswerQ: vf39 in the future?  zdez 1 year ago

    I plan on swapping out the td04 on my 2002 wrx with the vf39 on down the road. Would this fuel pump be the better option between the 200 and 300 series pumps?

    • A: For a VF39 the 200 is plenty, however it will not hurt anything to have this 300
