I used these to replace the original o rings on the fuel injectors when I took them out for a cleaning.
2004 Taurus 3.0L

Caveat emptor these are only for the top of the injector. Nobody will tell you this and hardly anybody knows. After these failed on the bottom of 3 of my fuel injectors I put the old ones back on. There's a good reason the oem are blue on top and green on bottom. The only way to get new for the bottom is to get new injectors. You can call fel pro and find out foryourself or take my word and save those green ones.

I'm in process of cleaning up the injectors on my '02 E-250.
Advance's system says "2 per vehicle", meaning two packages of these.
If you've got a V-8, you'd best get 4 packages because there are only 4 seals per package - since injectors use 2 each, that adds up to 16 in my book.

I'm sure they'll work fine. I'll update if otherwise.

      2002 F150 5.4L. Put grease on o-ring ,but changed my mind. fell out of rail to easily. Had to pull rail off of new intake to get to coil bolt under pressure regulator, but went back together smoothly with no leaks. Why 4 to a bag, why not 16?

      For all the review comments about not fitting the lower o rings on the injector...read the discription. Upper O Rings. It's in Black and White. Quality oring and a must do for replacing those knock sensors on a 5.3.

      Enough for two injectors per pack. So you need 4 packs to do a v8.

      Does not fit bottom of injector (head mating surface)

      Comments about Felpro Fuel Injector O-Ring Set:

      Does not fit bottom of injector (head mating surface). The part said it fit my 2006 Jeep Grand Cherokee, but this is only the top gasket. Though the description doesn't say it anywhere. When I took off the injectors the top O-rings looked in great shape so I didn't mess with them. What I really needed was the bottom injector o-ring, but Advance doesn't seem to sell it. Make sure you are expecting the right thing. I returned these, and ended up just flipping the bottom o-rings. (the top side was cracked a little due to being expose to the air) I put it back together and it didn't leak.

        Comments about Felpro Fuel Injector O-Ring Set:

        So the contradiction between east to install and difficult to install you ask? Despite the AAP website claiming these o-rings were an "exact fit for your 2000 Outback" fuel injectors, the weren't even close. You'd have to trim off the outer two-thirds of the o-ring to get them into the fuel rail, let alone to seat cleanly, somewhat defeating the purpose of having an "exact fit". They were never going to fit. OTOH, the inside diameter was nearly perfect on the fuel injector and easy to install on the injector. But they are never going to fit on this car. The OEM part is on the left...

                    Hi Wjd, great question! Yes, this O-ring set is for the intake manifold side of the fuel injector and is an exact fit for your 1997 Ford F-150 Pickup. This could cause vacuum leaks in higher mileage engines. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                • Q:

                  How many o-rings do you get by ordering this? It looks like 3 so if you needed 6, you would order 2 of these? I know the intake manifold comes with 6, and I would need 6 more to replace all 12 on the injectors.
