ericem Posted May 15, 2009 Share Posted May 15, 2009 Hey, I am going to swap my fuel filter from my 93 legacy to my 94 legacy turbo (the one on my 93 was replaced not a few months ago) and I figure I should maybe backflush the filter with compressed air, good idea? Or just push out the excess gas in there with compressed air out the same direction it flows? Quote Link to comment Share on other sites More sharing options...
tcspeer Posted May 15, 2009 Share Posted May 15, 2009 Why not just buy a new one, or put that one on without using compressed air on it? I would be afraid the compressed air might damaged the wet filter. Quote Link to comment Share on other sites More sharing options...

Rooster2 Posted May 15, 2009 Share Posted May 15, 2009 I don't think any back flushing, or air hose can clean out existing dirt in a fuel filter, as the filter media paper is trapping extremely small dirt particles. My advise, if you want to reuse the filter, is to simply "shake out" any existing gas in the filter, wipe off any dirt on the inlet and outlet hoses, then install.

bheinen74 Posted May 15, 2009 Share Posted May 15, 2009 this is not standard protocol, unless you are stranded in the middle of a desert and the fiilter is clogged, would do this just to get you back on the road. The filter is a paper type which absorbs all the particles, once trapped, there is no way to dislodge the sediment from the filament. Do you reuse burned out light bulbs, NO. same on this, it is basically the most critical part of the car. if the filter is newer, than just install it, do not blow air thru it. It will be fine as is.
