Upgrading Injectors, what gaskets should I replace?

[confuzed240]

Upgrading to 550s on my SR and wanted to know what gaskets should be replaced while I have them out. Its a s13 blacktop. Thanks

Its the O-rings around the injectors themselves that are always in question. Make sure to lube them well so they don't get hung up on their way into the manifold.

I bought new SARDs so are you talking about the o-rings already on the injectors. Or is there another set that go into the manifold that need to be replaced.

[s14unimog]

no... just the o-rings on the injectors themselves.

yes i heard to use the oem rings and not the ones that come with the injector. and you some sort of vaseline?
