I had to change the fuel filter on my '04 STi and I figured I might as well upgrade my fuel pump while I'm in there... This kit comes with everything I needed. Direct fit. Easy to do.

Just got this because my old pump was failing and was causing a lean condition. It's like everyone says it's loud but you know its working. My cars stock and this is Definitely worth the upgrade, doesn't bog or hesitate at full boost. it takes around an hour to do yourself. Just be careful with the level arm putting it back in. Your gonna need the upgrade eventually just get it

Works well, tight fit.

Works great. Was a tight fit into the 2002 WRX fuel pump assembly, but I didn't have to shave or bend anything, just mindful when putting it together. No issues at all, though.

Installation is pretty straight forward. Only issue was that the pump itself would not fit with the rubber grommet used to hold it in place. I left that out and used a zip tie instead. Don’t notice any louder noises on start up. Great product as always.

Good Kit

I've used this kit on previous Subaru projects, and when starting a new project I always like to start with the pump. very easy install, and it's reliable. The filter that it comes with doesn't fit the slosh box in the STi configuration, so be prepared to order an OEM sock.

    I'm installing this pump into my 03 wrx and was wondering do I use the old harness on the stock pump or the new harness in the kit?
