My 90 Loyale sprang a fuel leak. The "fuel damper" rusted out. It is located right beyond the fuel pump. No dealers stocked it around here and none could say that it regulated anything other than noise. I disconnected the bugger from the fuel pump and substituted a 3/8 fuel line hose with clamps. I'm no longer leaking but does anyone know if there is any purpose that this $45 item served. The car seems to run well so far but remember the story of the fellow who fell from a skyscraper... at every floor they heard him yell out... so far so good!

If it's not a filter, or a pressure regulator, and your getting fuel, I would say file that little sucker in the round-file. One less thing to blow up later....

If it's what I think your talking about, then it's actually a fuel damper. What it does is smooth out any pulses from the pump. It may sound like a crucial part, but not really. When I plumbed my truck for F.I. I didn't have one, so I went without. If I intently watch my FP guage, I'll notice a very slight movement in the needle, but it doesn't effect drivability, and has been like this for many months now. You can do without it.
