so, I bought an old rotorsports secondary rail and accompanying 1600 cc injectors. When they got here I noticed that they included the stock diffusers which fit on the injector perfectly. I'm not sure what to do right now, as I have the LIM spacers and 4 stock diffusers.
Should I:
A) clip the prongs and basket from the diffuser and use it as is

B) do the same as above, except instead of the top o-ring on the basket, use the LIM spacers instead

C) use the diffuser with the prongs and basket

D) use the diffuser, prongs, basket, no o-ring, and spacer

E) don't use any part of the diffuser and just use the spacer (least likely option as it doesn't appear to seal correctly, if at all)

F) diffuser, prong, basket, o-ring, and spacer (not likely either because the injector doesn't appear to sit as deeply which I don't really like either.

F) another option that I'll listen to advice on

I like option A or B the best, but what do you guys think?

 

middle of the day bump, anybody got an opinion?

 

I use spacers and nothing else, no sealing issues.

 

my problem is my injectors don't have an o-ring at the bottom like illustrated here

bump, still looking for a few more opinions/answers

 

I agree as well just use the metal seal, maybe just a little RTV as well.

 

using option E) without problems yet...

 

thanks guys, today is the day, lets see if she passes the sniffer test

 

Check damian's thread:

Basically, he used (A) in your choices.

 

thanks mahjik, during my search for info that's one of the threads I read.
and since the spacers didn't fit in my LIM at all (they're too big) I went with A
