I have a set of fuel rails at home that were supposed to be used on my car to allow the use of AN hose ends and braided SS hose.
However, I don't really understand what they are...
I included a drawing of the rails I have now (on a J-spec S5), and of the "new" rails. I obtained them from Eurorotor, where they claimed they were 200hp (= S5) rails. But as far as I know, S5 rails do NOT use banjo bolts or removable pulsation dampers. Mine sure on't have that. And on the FC3S pro site, they clearly state S4 have removable fittings, S5 not.
Another strange thing is the "hats" that fit the injectors. These are different from the rails I have.
What bothers me most though, is the FPR. On my rails this is welded on, and has one vacuum line connector. On these new ones the FPR is welded on (all 3 other fittings are bolted on) and seems "double" with two vac ports???
Anyone who can identify these? Perhaps Higgi, our FC master? And what are the two vac lines for?

 

Not to flame your drawing skills, but looks like a S6 fuelrail to me...

I'll have to check at home, i got S4, S5 and S6 fuel rails.

 

I think they are FD's, FD fuel rails use banjobolts to connect.

 

Mireck, my drawing skills with MS paint are not as good as with a regular pencil and paper (yep, I'm very old-fashioned) but I think it should be good enough to point the difference's. So you might be very right these are FD rails. I thought of that myself, but would have guessed they wouldn't sell me FD rails for FC money.
I don't think I can use these rails on my engine (and with my injectors)??? So if anyone wants to swap them. What I do need are (cheap) S4 TII (180hp) rails, because these are allowing me to use AN threaded connectors with metric/AN adaptors.

 

I can take some pictures of my fuel rails (FD) for comparison. I have them separately from a spare engine. Will post tomorrow (Saturday)

 

Hmmm...hIGGI disappeared?

The second pic looks suspiciously like the fuel rails off the S5 (Phenix's car) that I worked on while I was up there in CZ.
I remember the little "hat" things over the secondary fuel injectors.
I didn't understand what the double vacuum fitting on the fuel rail was for also.

So you don't happen to remember how they were connected???

 

Double vacuum outputs are on S5 TII fuel rails (on european) it was talked and explained here on european forum, being it same or similar to EU spec FD FPR

I dont like them and i do not use them on any car. Whenever possible, replacing it with S4 TII fuel rails.

 

...which was what I wanted to do in the first place. I actually wanted to use S4 rails so I could later convert to an aftermarket FPR and parallel rail setup.

 

go ahead
