Dealer doesnt have diagram for my 97 318i fuel rail and I need o-rings??

[318iyiyi]

My 97 sedan with a 318i has steel fuel lines that thread into the fuel rails. Both inlet and outlet are threaded and have o-rings on the tips of them where they go into the fuel rail, but, when I look on realoem, only one is threaded and the other has a nipple on it that takes a rubber hose.

I have checked ALL years and option in the E36 USA series and some UK series but they all show the same thing. I called the dealer and they also have the same view. Dealer said "its probably a generic view. Mmmmm, okay, I understand that, but, how do I know what is the proper o-rings if there is no proper listing, either in an exploded diagram, or, there are no notes about dual threaded fuel lines??

Anyone else ever run into this?

Thanks

To help you check this it might be good to have the VIN. Because we even do not know which country spec your car is, as "Location: left side of sanity" is unknown.

Sorry

Realoem = classic, E36, build date 6/1997, sedan, 318i, USA, M44, Automatic

#9 and #10 if one of those isn't the one that fits on top of the injector then they are probably only available with the injectors.

If you look at the year unspecified version of that diagram, it's easy to see the revision occurred for 1/97 production on.

From the listing of the parts that went AWOL, it appears that the FPR was removed from the rail and revisions were made to the inlet/outlet pipes. Looking at the supplemental notes, this was done for CARB TLEV (Transitional Low-Emission Vehicle) standards.

The feed pipe does change at that transition, but the inlet o-ring remains unchanged. So it's a good bet the feed o-ring is PN 13531247953.
The diagram is generic, but the parts listing shows the rubber hose and clamp removed and the return pipe changed. From this I gather that the threaded pipe you have is the 13531433830 part. So now we need to figure out what o-ring is used here.

The same revised rail and return pipe was also used in the Z3, but none of those diagrams indicate anything specific. Now you're just going to have to go with a best guess. Are the feed and return line the same diameter? Then it's likely they use the same o-ring.

It's not likely to be these. The OP is talking about the feed and return line rings and not injector rings.

My bad, should have read more carefully.

Seems like you spent a little time on my issue and I thank you immensely. To be honest, I missed everything you found/dug up, but, the only option I had was to just order the o-ring and find out. I have my second parts car I am able to pull an o-ring off to see and match up.

I have the new water pipe back on and the lower manifold hooked up. I didnt see an o-ring on one pipe and think it is in the fitting. I am going to throw a battery in there and see if it leaks. I need to get her running long enough to get it home. If not, I will order those o-rings (actually doing it now) and have them ready to go one way or another. I was hoping to find the right diagram, but, I will take your info and roll with it. Thanks again.

Been there and done that, lol.

I threw a battery in the car today and jumped the relay to get the lines primed. No drips, so, the old fuel rail o-rings are holding, for now. Its just a beater get around engine from spot A to B until I get the other engine built, so, no big deal, but happy no leaks. Like I said, I will have some new o-rings, which I already ordered, by Thursday and can match them up to see whats what. I will post up what I find so anyone with this headache can either rest easy, or, have an idea what to do next.

Thanks everyone.

A final update to this saga for all those that are curious. If you have the in/out fuel lines that both "screw/thread" into the fuel rail, the o-ring #12 13531247953 thats in the diagram is the correct o-ring for both. I have physically matched it up to the old one from my fuel rail and its the same diameter.



Thanks for all the help guys, appreciate it.
