    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.

    Upon opening the package. I noticed the O-Rings were round but had a little bit of a oval shape to them. didn't think it would effect the injectors but it did. leaking on #1 and #3 injector. so i had to go out and buy another set. Now i replaced those with the new ones and worked fine. They do the job but be cautious about the shape of the o-rings.

          These orings are fine for replacing the top used orings of the injectors, but DO NOT WORK FOR THE BOTTOM INJECTOR SEALS.

          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.

                                  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.
