Whats the desired way to install EV14 injectors?

[infinkc]

Use hats and spacers?
Change the lower o-ring with a stock size one with no stock clip?

[Mrdeezy]

I just did mine today. I used clips with no hat or spacers. No leaks seems ok.Turned sideways awe style with uscar adapters.
I think there are 4 different lengths so be careful what you order.

[durfA4]

Mine are 52lb installed using oem injector o-rings and clips facing same direction as oem. Fit is perfect.

[ThePeoplesChamp]

I did oring and clip and they seated perfectly

[GWerks]

O-ring and stock clips, just like if you were installing stock injectors. No leaks for me.

[Korben007]

If you wanna get the nozzle way down in the hole you gotta get the rail spacers and injector spacers swap the stock o-rings over.

[jibberjive]

The o-rings seemed fine for me, and they fit well enough for me with no spacers. I'll check for leaks when the car's running for sure though. Word is that you're supposed to twist them so that the connector is parallel to the rail flow for best spray pattern. Just repeating what I heard.

#4 grind manifold posts down 1/8" -1/4".

[Mikse]

is it common for EV14s to have leaks and therefore you should change the lower O-ring? I´ve never heard anyone changing anything but the reason why I ask is I have huge boost leak between one injector and intake manifold. Haven´t checked yet is the O-ring seated properly but they were lubricated before install.

Can someone post I pic how the OEM O-ring differ from the EV?

Definitely get the injector hats. When tuning at 2nd gear WOT, 2 popped off the fuel fail since it was too small.

The ev14 o ring on the bottom is smaller than a stock one. You should change them.

[Mikse]

So basically I could swap lower O-rings from stock injectors? Is the O-ring´s inner diameter same if I take the OEM as a model to buy correct size?

[Mikse]

Changed the lower O-rings to thicker OEMs but I'm still leaking from one injector. As there are more than one type of EVs there are also different length injectors. My EV14s came with EPL fueling kit but don't exactly how long they are. Can someone confirm should or shouln't I install these injectors with spacers between fuel rail and IM? I have rs4 intake manifold and fuel rail. At the moment I have 5mm spacer between fuel rail and manifold because it look that the injectors would go too deep inside the manifold without spacers.

[FlyboyS4]

With injector hat and fuel rail spacer.

[protocol_droid]

The EPL (KO4) kit comes with injector hats already installed, spacers for the fuel rails and you use the stock injector clips. There was another post by 034 that confirms this somewhere if you search.

[Mikse]

Is that with RS4 parts or oem? It looks that the lower O-ring needs to come out from the "tube". How thick fuel rail spacer you have and do you know the length or you injectors (or are the from EPL so same as mine)?

I believe EPL K04 kit is ment to use with S4 rail and manifold but RS4 parts require shorter injector and thats why there is no need for hats.

EV14 injector, I did not measure the length. EPL hats and spacers, stock manifold and fuel rail.

I did this same setup. Have had zero problems. 034 did a nice job of providing all the proper parts. The OEM orings just got a little more meat on them. I didn't like the way the Bosch orings felt a little loose. The OEM are so close in size but a little more snug. Have had zero leak issues.

Thanks for the link but the difference between S4 and RS4 parts is that OEM RS4 injectors are only 38mm long so If I'd use hats I'd need even thicker spacers.

The picture flyboy posted the injector is much deeper than where the stock injector is. I quess I just need to install the injectors as deep as they go inside the RS4 manifold and hope theres no leaks...Or I have faulty manifold

Ah, didn't see you have an RS4 manifold... my apologies.

[jibberjive]

Heads up, I change my opinion from above. Do what you can to preemptively avoid leaks. I installed mine with no spacers, EV14 o-rings and had a pretty bad leak or two. Took everything off and ground down the fuel rail posts 1/8" - 3/16" and reinstalled. I have to double check now that it's been a minute, but that took care of the lower leaks. [It was a huge pain though, because I first started shaving the posts down with the intake mani installed on the car. I cut a wire to the coilpack with my grinder, and the thing I was using to cover the intake ports came off. Needed to repair the wire (obviously), and take the intake mani off to clean the debris out of the intake ports. No fun. So yeah, just deal with it up front.]

[Austonwerner4]

I had the EV14 O-Rings on and no clips and they were super loose and leaked. Got new O-Rings from the dealer and installed my injectors again with no clips and they are super tight.

[sweets4style]

This is full of half truths. You can:

A. Certainly run purple spacers from ID or similar size other brands on the injectore tops. You then do not need to run clips (in fact cant) and replace the bottom o ring with a stock sized one since the ev14 ones are a touch small.
B. You can install the injector without a purple size filtering hat (ID talk) and use the injector clips and replace the lower o ring with an s4 one. This seals perfect and puts it in the hole quite deep

You do not need any fuel rail spacers of any kind. You do not need anything but injectors technically and you reuse the stock injector clips and lower o rings if you are cheap.

I promise this is the truth listed above.

I haven't gotten around to my 605 install yet, but I'll ask the masses about my setup to be sure I'm prepared.

I got 72lb injectors, clips, hats and fuel rail spacers/hardware with my EPL kit. Since you say I don't need the fuel rail spacers, but to replace the Bosch o-ring with a stock o-ring, are they including fuel rail hardware just to call this a "complete kit"?

It makes more sense to install the purple hats and leave the spacers out to ensure a snug fit. Maybe they're included just incase you decide to retain the Bosch o-rings for 'that much more'? Not exactly sound logic if this is the case.

I think I will install mine with hats and stock o-rings first since it seems to be the concensus...

[julex]

There must be some difference between early and late (A6/allroad) style manifolds as mine sit just fine and don't leak in my allroad. The bosch o-rings (whatever color they are, I am using 1000cc injectors) are in pretty tight, no looseness anywhere.

Maybe early style manifold has slightly larger holes.

[sweets4style]

I have installed ev14 injectors in both early and late style manifolds as well as an rs4 manifold, although it was using a stock s4 fuel rail on top. I have also installed the ID 850's which are an LS9 application which are shorter but they do indeed need much longer adapters. The standard length ev14 that you get from most tuners and ID etc require no spacer but should have the lower oring changed for good measure and the clips to be used. I personally like the shortest ID (purple) hat because it has a 9 micron pre filter thats replaceable and built into it. Just a nice added feature. When using them you do no use the injector clip. The injector will sit flush with teh fuel rail cup up top and be quite a bit into the manifold.

If I took pictures during the installs that actually showed any of these with clarity I would post them but I didnt.

Absolutely no clips required, huh? I wonder why EPL would send all this stuff if we don't need it?

[DaveM@EPL]

For S4 intake manifold and fuel rail, the injectors use the ev14 orings that come installed on them, with the hats, spacers, and clips. For a while now we have been shipping hats that allow the use of the clip for the fuel rail, as well as a clip to keep the hat attached to the injector. Every set lately has been leaving the shop with the hats already installed on the injector to help avoid any confusion.

The oring size difference isn't the problem; its that the o-ring height on the EV14 body is slightly higher than the OE injector, so if you were to install the injector into the fuel rail without a clip and bolt down the fuel rail, you'll notice you can move the manifold side o-ring in and out of the manifold. The spacers and hats may seem like a weird combo, but with both those installed there is no chance the injector can move around.

RS4 fuel rails and manifolds need a different size spacer, but may not require the hats (it's been forever since we've even had a car through the shop with an RS4 intake manifold and OEM RS4 fuel rail).

that made it simple stupid. I loved it, I hate thinking at night

[sweets4style]

Ok you forced me to put the time into picturing this for you all since we are gettiong incorrect info.

I will do both stock s4 fuel rails on both box and spider look manifold and do it with the clips and no spacers and then without clips and with spacers.

YOU DO NOT NEED ANY OF THESE above mentioned WITH EITHER MANIFOLDS.

Yes, I'm bringing up an old thread but doing so for documentation purposes.

I did as Dave said above and have zero leaks and everything works as intended. I have the EPL Stg3 fueling kit with an S4 fuel rail and S4 intake manifold. Ran the EV14 o-rings, hats and spacers. Clipped the hats to the injectors and reused factory clips to clip hat to fuel rail. Needed a few shims to bolt the fuel rail down which was included in the kit. Zero fuel leaks. Injectors sit snug.
