Anti-backfire valve


Recommended Posts

Hello Ratsun land,


I recently bought a 1978 620, and I'm trying to get it all put together so it will pass emmisions. (All the emissions stuff was either missing or disabled when I bought it) So far I have been able to find everything I have needed EXCEPT for an anti-backfire valve. None of the parts stores even list it.


Does anyone know where I can find a new anti-backfire valve? Or is there another name for it? Or an alternative part that does the same thing? Or does someone have a working "spare" that they would sell me?


Thanks in advance for the help,


Ben Jones

Thanks for the lead about the Nissan dealers...


I ran it through once and failed the visual inspection and the loaded tests, and barely passed the idle test.

Now I'm not even sure they even consider the anti-backfire valve part of the emissions equipment, so maybe I can try taking it in without an anti-backfire valve, and see what they say.

Do you think they'd fail me if it was backfiring every time they shifted? ;)
