Default FAST LSXR Injector O ring

After a good hour or so of searching around....


Does anyone know what size fuel injector o rings are needed to fit the stock style injectors onto fast rails and the lsxr 102 bottom? Ovbiously the FAST ones are the correct ones.....looking to see if I can pick some up locally rather than ordering them.

this thread may help. i'm assuming you have ls1 style injectors. if you have ls2/3 style the stock orings for them will work fine

I am either an idiot or this is actually confusing...

01MAROONz2890 - I dont see a link that you posted.

And the link above from redbird gives me :
146020COR - is this the correct part for the LS1 style?

Glad I found this thread. I was unaware I'd need a fatter O-ring. Called FAST just to verify 146020COR works on LS1 style and they said it will. As if I haven't spent enough money on this hunk of plastic I will just continue adding to my tab.
