Default Can I reuse fuel injector o-rings?

Did a search and didn't find . After 10 minutes I gave up.

I'm putting the manifold back on the car and I read somewhere that you need to use new o-rings if you take the injectors out. I went to the dealer and they only have them seperately if it's a 3.4 liter. If it's the 5.7 you have to buy the whole injector. The o-rings look in good shape, I'm putting them into an aluminum (Weiand) intake. Any problems? Thanks.

re-use them, just be sure to inspect for nicks or cuts and use Vaseline or grease before installing them

I reused mine during heads/cam swap this week.

Everything is fine. Just be careful, and inspect them like he said.

If you have a bad one you can buy a set of orings for a 90 ford mustang from kragen or autozone for like 8 dollars. It is the same size as the ls1 injectors use.

That might come in handy someday. Thanks.
