Walbro 341 / 342 Fuel Pump for 2004 WRX STI

[Niran]

Hey All

Hoping to get some feedback. Ive been scouring the forums to try find some info on fuel pump compatibility. The general consensus is that the perfect fit for my car is the Walbro 342 pump, but the ones on trademe are all 341s. I've read the difference is not that big and they will still fit. Now i don't have a whole lot of experience working on my car and was hoping to do the swap myself. Is changing the pump with a 341 a mission? Or is it straight forward like the 342?

Was hoping to get this one:

Pretty cheap, bit weary if its genuine or not, but he has pretty good feedback.

Any comments / past experience would be greatly appreciated

Better to buy a better pump from a reputable company. This is still cheap http://www.speedtechnz.com/shop/Fuel+Pumps/Deatsch+Werks+500hp+Intank+Fuel+Pump+for+Subaru.html

Nz performance used to cut a good deal on genuine walbros. Ive used 41 last couple ive had as he was cheapest and genuine. If he has them in stock thats another option.

I have a 2002 WRX and fitted a Deatchwerks DW200 with no issues at all, using the stock pick up sock.

+1 on the DW200, fits my V7 no worries.

I used DW200 - just make sure you use factory sock - or you will end up with surge problems when going around corners with half a tank or less

Right so is the consensus that the dw200 is a better quality pump? And it's better to use the stock fuel filter? Even though I've done 130kms?

Nothing wrong with either walbro or dw. Aeromotives another one to confuse you and better than both.

The genuine sock sits lower in the tank than the aftermarket ones that come with new pumps. Dont worry about it being dirty unless it actually looks choked up.

Right so Walbro or Dw200 or even aeromotives are all good pumps. And use the stock filter. If I do go with the walbro, Is there a big difference in installing the 341 vs 342?

STM tell me that walbro is okay at first but don't last long... 5 years and the pressure is decreased.
