HI guys, Im just about to upgrade my fuel pump in my 2001 Subaru B4 Liberty.


I purchased a Walbro GSS342 500hp fuel pump.


I have heard to get it to fit I need to put a small dent in the bottom of my fuel tank, as apparantley its slightly longer then my stock pump and also use my old fuel sock from the old pump.

Should this pump just plug into my fuel pump connector loom or does it need to be rewired?


Has any other B4 owners installed this pump if so please tell me your thoughts or installation advice.


Cheers Aaron

Sorry I can not help you with a Walbro install.

I fitted a DW65C, only took like 20 mins and no mods needed at all.
