I bought a set of metal injector insulators spaced out for using LSJ injectors on the l61 03+ fuel rails that slowfire01 makes . I need some new o-rings for LSJ injectors. This kit is for the LSJ do you think it would work on my L61 with LSJ injectors?

I don't see why it wouldn't as I am running the o-rings that came on my injectors now with washers spacing them out (ghetto I know). Just double checking before I buy it.

if you just need the o-rings a local auto store should have then, I picked up the same thing at an Advance for mine.

I need the orings for the insulators too.

Generally speaking you can use the old ones off the plastic cups from the originals, if not you will have to take them to the parts store and get some new ones, reused mine just oil'ed them a bit.

I can try to use the old ones from the plastic cups I guess. (I have a set from the cobalt ss they came off). I just figured you had to replace those every time like the injector o-rings.

you dont have to replace injector orings everytime. that would be a waste. just be careful with them, and lube them up when reassembling them, and all should be well.

who ever told you that you HAVE to use new ones was high on crack.

Correct, no need to use new ones, unless they are bad, which rarely happens.

the only reason I got some is because they were missing, guy I bought them from must have removed them.

Cool I'll just re-use then. Thanks guys

Yeppers. what did you think of the injector spacers?
