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.

    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...

            If you plan on getting these for fuel injectors on a Volkswagen. Don't! They are too big. they will tear while trying to press them in even when lubed.

                    Great O-Ring set, used them on my Explorer 4.0 OHV, make sure when installing that you lube them up and first install into fuel rail and then press into intake manifold, otherwise you're going to end up damaging them and replacing them again.

                        Buy enough of these to replace the upper and lower on each injector. Easy to do and short installation time. Might as well do them all. They are sturdy orings.

                              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.
