I know there are already many threads out there on this topic, but I have something new. So basically I have a LQ9 crate motor and I’m swapping it into a third gen f body. The pickup tube that came with the motor had the recessed part for the thick red o ring at the end. My new Holley 302-2 kit does not. The o ring that came with that kit was no where close to ever being pushed in and I don’t know why. I took the stock red o ring (the fat one) and it snapped right in. I threw everything back together and had great pressure while priming the engine with the starter at 35 psi. Then after looking into it more I started panicking since the fat o ring isn’t meant for a straight pick up tube. I ripped everything off again and now I attempted to put in the blue o ring. It doesn’t snap in at all and does not sit flush with the pump unless you tighten the bolt. Any ideas on where to go from here? The red o ring that I pulled out was just fine so I probably just wasted all this time and money. The red o ring also took some pressure to get it over the pickup while the blue one is fairly loose fitting on the tube.
Last ls1 i helped a buddy piece together we used the red thicker o-ring on a pickup that's supposed to take the blue o-ring. Works 100% fine and he still has proper oil pressure after months now. I actually prefer using the red one as it's a tighter fit. You just have to make sure you seated it properly. Lubricate the o-ring and inside of oil pump with engine oil when installing makes it a lot easier.
I've also just finished installing my own LS2 into my own car and i should be starting it next week. It would have been sooner but i'm waiting for a few parts i needed that were different on the swap over. I used the thicker red o-ring in this engine also where it's supposed to use the blue one. It was a bit more difficult to get it seated with the 4th gen oil pickup compared to a different pickup that the engine i mentioned in the first sentence was using, so i'll let you know if it didn't work out.

The red definitely has a much better fit on my engine, so I’ll probably just end up throwing a new one of those back in. There’s just so much misinformation on this topic out there. Thanks for the advice man.
Well i started my LS2, i got the parts i needed from somewhere else. Another red o-ring success. I'm very happy with the oil pressure. It's going to need a lot of tuning. It's running small bore ls7 heads with titanium valves, 243/250 .660 108 +2 cam with 30 degrees overlap. It sounds insane. I didn't get a vid yet, i still need to tune it so it can idle.

That’s good to here. Just picked up a new red o ring yesterday so I can move past this whole thing. I should of just left it when it had 37 psi at cranking lol.

Yep you won't have any problems at all. As long as you install it properly.
