Wizzurp Posted January 29, 2016 Share Posted January 29, 2016 Ok had my fuel outlet line off the pump come apart on me earlier today. Had some spare tubing in my car so I ran it straight from the pump to the feed hard line so I bypassed the fuel pulse damper. I guess what I want to know is will this have any sort of detrimental effect? Wideband seems to read the same Quote Link to comment Share on other sites More sharing options...
Snailed Posted January 30, 2016 Share Posted January 30, 2016 It can cause driveability problems but a length of rubber EFI fuel hose can have a similar effect as the damper so you might be fine as-is. Generally a return style fuel system is less likely to require a damper but many OEMs included them even when return style fuel systems were the norm.

Wizzurp Posted January 30, 2016 Author Share Posted January 30, 2016 After I wrote this post I realized my rb20 fuel rail has a damper built onto it along with the fpr on the back end so I think it'll be perfectly fine. I was curious to see how many people do away with it or keep it and what their reason was though. Thank you for the reply! Quote Link to comment Share on other sites More sharing options...
