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

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
