I have to take my passenger cam cover off this weekend and replace the breather valve O rings cause they are the wrong size from Porsche (a whole different story).

The main problem is the hard fuel line that runs over the cam cover. It is a PITA. Do we really need a hard fuel line here. Can't we just replace it with a flexible line? Have a local hose shop make me one or something?

It just seems like something that is still there because it is there but doesn't have to be if you want to replace it.

What have you guys done to replace this part. I think I heard it is NLA also.

Thanks

Greg Brown makes a hose that does away with the way that Porsche routes that line.
Look at Robs last post on the oil control issues and the FIX for that and you will see.

What you wont see is the quality of the hoses from the pictures, you need to hold them in your hand.

One is going on my car if I can ever find time to install it.
Actually the whole set is going on my car, and my lines are less than three years old, they are that good.

Thanks PM'd the people in the know to get one.

You WILL be impressed.

Gregs is the only thing I'd replace it with.

You could just put EFI hose there, but with the length and other crap in the way, it won't last long.

I managed to pretty quickly weasel that return line out without a whole lot of effort. I had more fun getting the rear diverter bracket out the first time. The Hall sensor turned out to be pretty simple with a 6"-long hex driver with an extension that moves the drive end behind the shock tower. A little dum-dum putty in the end holds the Allen screw to the driver. Tied the vent hoses to the fuel rail with cable ties. Getting the cover off and on after all that was a piece of cake...

Thanks Dr. Bob. It was super easy to install . . before i put all the crap back on the engine. Those mis sized o rings really are a pain in my ***.

FWIW, I smeared those o-rings with Hylomar before installing the plugs and vent elbows. A little extra insurance. Hylomar stays gooey and seals even when stuff gets hot, so it seems ideal for this duty. A couple weeks and a couple hundred miles, so far so good on mine.

I went with steel braided line.

I like your setup but I don't have those beautiful fuel rails and I don't see your FPR at the front. How did you handle the removal of that. I'd love to eliminate some of the plumbing but don't know where to begin.

I did exactly the same and replumbed the RRFPR to the rear passenger side by the expansion tank. I still need to fabricate a bracket for it though...

Let me first say none of this is tested yet, the engine will go in the car in a week or so.

You have a fuel dampener at the drivers rear which I have also removed.
There seems to be about a 50/50 opinion if they are needed.
I am sure Porsche would not have used them (2 of them) if they did not think they were necessary.
I could end up with damage to something in the system but I am going to monitor it.
A few here have had no issues, yet.

I would leave your rear FPR and dampener at the rear stock and just remove the front one but to change your front line you have to customize it your self and if it leaks your car could burn.

What I did is I removed the old fitting from the old line and reused it as you will need it to attach to your stock fuel rails.
I needed it for my stock FPR.

If you are having problems maybe one of the vendors or guys with a shop will build one for you.
I did not have any luck as mine uses a product that has a possible issue, so as a mechanic I took it upon myself to modify it



I brazed the fitting to a new pipe

^^^ Worm gears clamps on FI hose is a big no no.

And really a no-no on real SS braid hose.

BTW, Greg Brown makes a really nice hose to go there.

Mac's had to do an amazing amount of modifications to this "kit" to make it work 1/2 as well as he has so far. Gee, wonder where he got it.
