Hey guys

I always feel a weird knocking sound from the chassis when the car is idle and I went to the auto repair shop they told me it may cause by the bad fuel damper. You can actually feel the pulse from the fuel line and its exactly the same rhythm as the knocking noise. Anyone have any idea how much the fuel damper cost? I am planning to import the parts from US but not sure they are the same or not. BTW I am thinking the fuel damper should be the same model as 350Z...anyideas?

It's a known issue with the VQ engine and I've recently replaced mine with a damper from Riverside Infiniti USA.

They sell for about $120AU shipped. Local dealers wanted $300 for it...

Thanks for your information. Can you please tell me where can I order one from? May be I can order one from US and ask someone to put it in. :D

The one that's usually faulty is on the left bank (when facing the engine) and has the rubber hose that feeds straight from the fuel line.

Part number is 22675-AM60A - Fuel feed hose damper

Another thing you can do to test if the existing damper is faulty is to touch the fuel feed hose from the damper during idle.

If it vibrates a fair bit like the noise from inside the car, then its faulty.

I think I may also need one of these, which fuel damper is generally the faulty one, as there's one for each bank?

Thanks for that. I never try to buy part online before, can anyone please tell me how to do? Is that just contact the guy by email and transfer the money to his account then he will sent the part to you? Cheers. :):D:D:P

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
