Rubber nub on S5 Pulse-dampner
So I bought a lightly-used set of fuel rails and injectors, and they just arrived in the mail. I was examining the PD just to check it's condition and noticed that a little rubber tip fell out of a hole in the top of the PD housing. Is this critical, or should I just plug the hole with epoxy? I tried orally pressurizing the rail and it seems like air isn't leaking from the hole.
Sorry for the crappy pics, a cell-phone was all that was available. http://sadpanda.us/images/261359-YBLA4QS.jpg http://sadpanda.us/images/261361-VYOGMJX.jpg |
Epoxy won't hold. It SHOULD be fine, but I would pressurize the fuel rail/PD with the fuel system and let it run the fuel pump run for 10minutes and make sure it doesn't leak.

yep.they are s5..
ok,,so sorry.. |
Please correct me if I'm wrong.
I think the part in question is on the end of the primary rail that looks like a pulsation damper. The pulsation damper is located on the secondaries and has the vacuum nipple. |
That would be the FPR on the secondary rails.

Does anyone know the rubber nipple on the end of the pulsation damper's function? |
