My fuel pulation dampener (S5 single unit) isn't leaking at the molment but since I have my manifold ripped down I was thinking about some sort of safty precation...

Has anyone tried clamping a rubber hose over the tip of the mushroom end on the damperer in order to re-route leaking fuel??? That way you would be able to actually see the fuel leaking from the hose when it occured and thus prevent fuel from spilling onto the manifold.

Post your thoughts and/or ideas...

 

buy an S4 primary fuel rail and get a banjo bolt to replace the very untrustworthy PD.

 

Just replace the whole fuel rail. Re-routing the leaking fuel isn't a fix to the problem, and yes, S5's do need to have the PD's replaced too.

The PD/fuel rail isn't that much more expensive than the S4 PD, so you're better off just replacing it instead of getting an S4 rail and PD seperately.

 

2 chioces for safety.

1. New pulsation dampener.
2. Banjo bolt.

Take your pick.

 

yep thats what i did bango bolt mod.. no regrets

 

can you buy those somewhere? if so wher?

 

You mean banjo bolts? Search for "pulsation dampener banjo bolt" and you will get all the info you need. Also see the topic in the Archives with the title "Skeptic of the pulsation dampener banjo bolt fix".

 

thanks aaron

 

yeah, if you can use the S4 pulsation dampener on the S5 I will most likely just swap it out and do the "permanent fix"...

those of you looking for the banjo bolt, i believe NAPA usally has them in stock...
if not, try

just make sure you buy some new crush washers too

 

I know this has been beaten to death, but i personally think you should replace the PD with a new one and NOT do the banjo bolt.

 

Luckily my PD was replaced just before I bought the car, so it only has maybe 30k on it.

 

i think mine went today!!!
i was driving down the road normally when i started smelling gas BAD...first thing i thought was the PD...i pulled over at a bar and opened the hood...the gas was so bad it burnt my eyes....luckily it didnt catch fire...i dont know how it didnt ...its still sitting at the bar since it was kinda late and i didnt feel like dealing with it..ill let ya know tommorow if its what it was or not

 

just my .02 cents... but, to keep everything working properly just replace the PD with a new one until you can purchase a new FPR with an integrated PD.

the PD is there for a reason... why take it out of the equation if you don't know the results?

Yeah, you need to dampen fuel pulsations.

Otherwise you're putting more stress on everything. Great way to cause fatigue failure somewhere in the fuel system if you get enough stress. - i.e., nothing at first, then after enough miles: kablooie. That's only if the stress is too high; but if it's not too high, then why is there a FPD? I'd rather just pay a mechanic $350 when it leaks every x0,000 miles and not worry about it.
