Stevethefolkie Posted December 27, 2007 Share Posted December 27, 2007 take a pick and post it - I've got a '91 Loyale and have no clue what you're making reference to .... Quote Link to comment Share on other sites More sharing options...
henrysteele77 Posted December 27, 2007 Author Share Posted December 27, 2007 it's a '92 loyale kind of looks like the one on the fuel pump outlet. no pics i'm at work. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 27, 2007 Share Posted December 27, 2007 I think he mean the Fuel dampner in the supply and return lines. SPFI GL/Loyales have 1 in each line very close to the TB. They are to "smooth out" or prevent spikes in the pressure in the fuel line, and provide a constant presure at the injector. However, many people have removed them without issue.

henrysteele77 Posted December 27, 2007 Author Share Posted December 27, 2007 Can They Clog Or Just Go Bad Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 27, 2007 Share Posted December 27, 2007 They can clog I suppose. Other than that, I've never heard of them going bad. I mention running without them, because they just get ommitted during SPFI conversions, or replacing of fuel lines sometimes. Quote Link to comment Share on other sites More sharing options...

mikeshoup Posted December 28, 2007 Share Posted December 28, 2007 Thanks For The Info Get Rid Of Them No one is telling you to get rid of them. There has never been a documented case where they have caused problems, except maybe leaking. Subaru installed them for a reason. Whether or not they are truly needed, well, that's up for debate. IMO, just leave 'em be unless they're leaking or you've exhausted all other items that could be causing a running problem. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 28, 2007 Share Posted December 28, 2007 They really can't clog - there's nothing inside them. It's just an open space used as an "expansion" chamber for fuel pressure spikes. If the pickup tube in the tank sucks air for a few seconds, these smooth out the fuel flow so the injectors see constant pressure. Removing them is just stupid. It's costly (FI line is expensive), and uneccesary. And besides occasionally rusting out, they never fail either. GD Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 28, 2007 Share Posted December 28, 2007 Thanks For The Info Get Rid Of Them No, All I meant wa that they aren't a "critical" part. Like if you found that it was actually clogged or something, you could ditch it, but there is no reason to do so "premptively". Quote Link to comment Share on other sites More sharing options...
