Fuel filter talk
« on: March 04, 2014, 08:55:20 PM »
I'm in the process of replacing my fuel pump with a DW 265lph thanks to Ray  :mrgreen: :mrgreen: I decided to take a quick peak at the fuel filter element to see what it looked like and it's pretty much black. I had a feeling it was in rough shape because I'm about 90% sure that's where my slight misfire / rough idle is coming from. While I have it apart, I need some advice on the best way to proceed.

Option 1: Replace with OEM 04+ in tank filter for about $100... and I have to wait for it to come in (which means I'm without a car for a few days).

Option 2: Ditch the the in tank filter and convert to the 04 WRX under hood filter. From the research I've done (about 2 hours worth tonight) it appears that there is nothing but good results from the 'conversion'. It seems as if the under hood filter flows better, is MUCH easier to replace, and is only $15-$20 and available at Advance Auto. The only down side I can find is that the in tank filter is designed to last longer... but I can get 4 under hood filters for the price of the in tank filter.... and it's a hell of a lot easier to replace.

Does anyone have any first hand knowledge on these? Are there any 'cons' about the 'conversion' that I have not yet found? I already have the WRX filter because when I originally thought it was the filter, I bought one from Advance only to find out it was the wrong one. So all I have to get now is some fuel line hose and a mounting bracket for the filter.

I don't have any proof that it's better, but every car I've had with an in tank filter has turned into a PITA come change time.  It was so easy to change the one on the '97.   I'd love to do this to my Legacy too -if if won't mess anything up.

Well I went ahead and did it yesterday. So far I don't see any issues. It will definitely make changing it a lot easier (if I have it long enough to have to change it again). I just have it sitting in there for now, but I ordered the bracket from the dealership so I can actually mount it once I get it.

Only benefit to having the sock in the tank is it keeps debris out of the pump assembly.
