LSXrT injector install help
 

Working on installing my LSXrT intake on my truck and I'm having problems with my injectors fitting. My truck injectors are too big to seat properly on the intake. Whats going on with that? Will I have to drill them out to get my truck injectors to work?

you should have got a second set of orings with the intake. i did not have to drill anything to get mine to fit

I got the new O-rings and they don't fit either. Too large. Too large for the smaller truck o-ring also. The injector hole is just too small for the injector to seat properly. Anybody else have this issue?

Wow that makes no sense. You OEM injector and oring should FALL into postiion. If thats not fitting you have something weird going on.

Post up a pic if you can. Ive pissed around with a lsxrt sooo many times I can help lol

You can see the small ridge inside the injector hole. This is as far as the injector will go. It only goes as far as the bottom of the fuel injector. The hole is so small that the injector head itself won't go past the ridge.Attachment 66609

Weird, I'm installing my Lsxrt intake today as well. My injectors seemed too small but the orings fixed that. I'm having a problem with the fast fuel rails not lining up with them though..

my mechanic fabricated some a/c orings and shrink wrap. i heard corvette ls3 or 7 orings would work.

I had the same issue with mine, o rings supplied were to bulky. I got others from a local auto store.

You say the injector Doesn't fit down even with no orings?

Yeah the injectors don't go in as deep on the FAST as they do the stock. Is that normal? Check out my injector photo. Does that look alright? Those are 8.1 marine injectors.

Mine sat the same as that
