Fuel damper replacement and inspection
Hi,
I'm about to replace my fuel damper as it is ticking. I saw people replace both damper and hose. I just wanted to assure, I don't have to replace the hose, right?
Second question - When I'll take out my fuel damper, how can I tell if it went bad? I mean, I know I can hear it and I'll replace it but how to inspect it to see the fault?

Question #1 - It's not necessary, but while you're right there you might as well. https://www.z1motorsports.com/fuel-d...ne-p-6389.html
Question #2 - If there's fuel in the vacuum hose leading to it, the diaphragm within the damper has failed.

There will be an abnormally loud ticking noise coming from the dampers themselves. With the engine running, place your hand over one damper at a time to 'feel' if those audible ticks coincide with the pulsating felt from that damper.
But I want to know how to inspect them visually after disassembly.

They are sealed units, so I don't think there is a way. With a vacuum fed system, you check the vacuum hose for fuel seepage as a result of a failed diaphragm; but with a sealed system I don't know of any other way to determine the condition of the diaphragm inside other than the abnormally loud ticking noise they would make as a result of the diaphragm not ''dampening'' the fuel pulses being sent there by the fuel pump.

OK. Thanks. The reason I ask is the price of these little craps at dealership - about 220$. So I though I could risk and buy a used one from some totalled car or something.
