Fuel line o-rings?

[ALamp]

Hi all,

In taking off the upper intake and fuel rail I failed to take good notes on the two fuel lines going to the fuel rail and fuel pressure regulator. Specifically whether or not either one had o-rings on them.

I know there's one from regulator to fuel rail. But also in the box the regular came in there were an extra o-ring.

It doesn't seem like it would fit the line that goes into the regulator itself but would fit in the back line going into the fuel rail.

Not sure if it's just a back up either in case the one that came on the regulator broke

Any advice?

I’m having trouble getting the fuel line to reconnect to the fpr also!

I ended up putting an o-ring on the back connection to the fuel rail and one between regulator and rail. I hooked the front line to the regulator without an o-ring.
It seems to be working as it should
