Message	Everybody that says they don't have issues don't really know for sure because they haven't measured their fuel pressure at the rail. There is no question the injectors cause pressure fluctuations in the rail. How much fluctuation is too much? Who knows... Nissan put a damper in the rail for a reason.
Follow Ups	Is there a better way to run a parallel fuel setup? - collegeboy 09:15:12 02/22/08 Why do you need to run parallel?

Thanks Don. - collegeboy 10:00:14 02/22/08 True the FPR will see the pressure , but #6 will - AZHeat 11:22:02 02/22/08 I ran parallel on my stock fuel rails. With this set up - AZHeat 11:08:37 02/22/08 negligible imho - aliaZ 11:39:16 02/22/08 Re: negligible imho - Guapo 11:49:24 02/22/08 link isn't valid anymore (n/m) - 550HPTT 07:30:25 02/23/08 You can feel them. The frequency is so hi it doesn't - AZHeat 11:51:34 02/22/08 I think what you're feeling is the actual injector actuation - aliaZ 11:56:26 02/22/08 I see what you are saying. But the OEM runs a dampner - AZHeat 12:37:36 02/22/08 no reason you can't continue to run the damper - aliaZ 23:13:41 02/22/08 Interesting links - AZHeat 00:01:17 02/23/08 probably a good idea to run a damper no matter what config - aliaZ 00:53:21 02/23/08 I run no damper on mine with 850cc and aeromotive FPR. - The Devils Z 05:30:12 02/23/08 Re: I run no damper on mine with 850cc and aeromotive FPR. - lonloud 07:32:18 02/23/08 Mike is correct in that the injectors do cause pulsations - aliaZ 08:44:15 02/23/08 I believe either way should be fine..
