I have a ‘79 280ZX that has a leaky fuel damper.  I have done many searches for the replacement part and have come up empty.  It’s been out of production for many years and there is no new old stock either.  So a couple of questions.  Does anyone know of a replacement part number that will work?  If no replacement is available, is the fuel damper really even needed?  From what I understand, it is there to dampen any presssure spikes or pulses that may come from the nearby fuel pump.  Thanks for any info guys!

There is at least one thread on the site somewhere about a later model damper that was used as a replacement.  I think it was available on Rockauto.  Maybe search the words using the site's search engine, or use Google and "site:classiczcars.com" as a term. 

I think that it might also make the pump last longer.  It damps the pressure pulses from the injectors opening and closing too.

Found the one I was thinking of -

 

Zed, thank you so much for finding that thread for me!  I was able to order the Bosch 0280161024 from Amazon of all places.  Pricey little bugger, but hopefully it will match up and perform as the original.  It may be a while before I am able to work on the car again now that the weather has turned, but I will post an update when I get it installed.  Thanks again!!!

For what its worth I have not been running a fuel damper for at least 3 years and I've had no problems. I have an aftermarket fuel pump though, so that could be the reason.

 

Good aftermarket Fuel Pressure Regulators have a damper system integrated. Aeromotive and Fuel Tech do.
