Hey gang:

I spoke to Rick Fenton, president of SX's North American distributor, today about their FPRs. Specifically, I called to find out whether it is necessary to retain the stock FPD when using their FPR. The website notes that the FPR also functions as a damper. There have been a few threads speculating about this subject so I thought I'd post Rick's response. For those of you that are in the market for a regulator I should also note that they sell direct to the public.

"Good Morning Chris,

Here is the information that the engineer gave us. If you have any further questions, please let me know.

Best regards,
Rick Fenton
President
FCP

Removal of OEM Fuel Pressure Dampeners can be done on fuel systems using the SX Performance Line of EFI Fuel Pressure Regulators. SX Performance EFI Regulators contain a light weight diaphragm assembly to help prevent fuel system chatter and provide pulsation dampening over a variety of frequencies. This dampening effect smoothes out pulsations created by fuel pumps and fuel injectors. Typically, the OEM pulsation dampener can still be used depending on the design and convenience of plumbing, although it is not required with the installation of the SX Performance EFI Regulator.

Chris:

All I can say is 'thank you,' finally someone has a real answer to this from someone in the industry. I have removed pulsation dampeners from three cars while upgrading the fuel system using an SX regulator and I can say I have never had one problem.

Don't mention it. I'm glad I have something to contribute every now and then. I saw a couple of your posts on this subject while searching the archive. Between your real world experience and SX's opinion on the subject I feel comfortable removing mine when I upgrade my fuel system in a few weeks.

 

Great to read. I've had no FPD for about 3 years after I replumbed with an SX FPR. Never any problems, but I have often thought about adding a dampener "just in case." Now I'm happy to forget about it.

Could this be archived? I think it is useful information regarding replacements for the dreaded pulsation damper.

 

We pull the pulsation damper on FC's all the time - no aftermarket FPR either - and it doesn't affect performance.
