Default Fbody pickup tube

I hope someone can help me out. I'm going freaking crazy. I'm trying to install a f-body oil pan #1255889 on a lq4 But the pick up tube seems to be hitting the front of the pan. I also tried to install the pan with just the windage tray #12558189 and no pickup tube. And the tray also hits the pan. I was told that this pan and pickup came off a 2000 Camaro. So is there another pickup that will work? And can I cut the windage tray to fit the pan? Thanks

The pan and pickup tube have to match the same vehicle.

If your using the F Body pan and pickup on an LQ9, you'll have to modify the truck windage tray...

Yeah I thought that I would have to cut the windage tray. But I also test fitted the pan with with the pickup with no tray. And the pan hits the pick up.

Yeah I get that. The guy who i got the pan and pick up said they both came off a 2000 Camaro. i went to the dealership. And i confirmed that the pick up is from a fbody. And they couldn't find any info on the part number from the pan.

So could there be another pickup tube that works with that pan?

IF it's an OEM pan, then yeah.

i checked my cd rom parts manual and to the best of my knowledge these would be original part numbers with no superseding....

pickup tube is 12558251 for 98-02 LS1 fbody

oil pan is 12558762 for 98-02 LS1 fbody

so the pan number in my book is different than the one on your pan, which you entered a 7 digit number and not an 8. i did find this tho when i searched that number

The pan for the Camaro and Firebird had a shallow rear sump (5.25?) that was squared up on the bottom edges. It's a 1255889 casting.

feel free to post the pics of your pan maybe that can help. i also have an fbody windage tray from my personal 2000 camaro if you were interested. but as stated the windage tray can be made to work.

According to http://www.improvedracing.com/oil-pa...8771-p-70.html
It says that 12558899 part number is a old gm number.

I have the pan installed in the car for mock up right now. As soon as I remove the motor again I'll post some pics.

Nope. Only changes if the engine has VVT or AFM/DOD or both. Then, and only then, it's a higher volume pump.
OH- Dry sump engines get a different pump, but that's a whole different system.
BTW, no such thing as a stupid question. Lots of stupid answers though.... lol

Awsome. That's what I thought. This is my first ls build. So I'm still learning the ins n outs of this motor.

I figured out my stupid problem. The pick up tube wasnt installed all the way in the oil pump. I had to install the oring onto the pump first then install the pick up tube. Then everything fit perfectly. This freaking car has been fighting me every which way possible.
Thanks for everyone who tried to help. Thank you.

ummmmmm i thought you were supposed to put the o ring onto the tube and then slide it into the pump? at least thats what i did. seems a lot easier to pinch the o ring doing it your way

I thought i had to put the tube and oring together. But I wasnt able to have the pickup mount flush to the oil pump. Install the oring to the pump was alot easier to install the pick up. And I was able to mount the pick up flush to the pump

ok can you confirm what o ring you were using, what color was it and where did you get it.

when you put the oring on the tube first it takes a good bit of pressure and a little bit of twisting to get it to go in, at least for me......basically when i just recently did it for the first time it kinda just went in after working with it for awhile, it never sat flush but it was most of the way flush to where the bolt seated it the rest of the way. but i do have some oil pressure issues myself that im assuming are not o ring related due to me having good pressure 90% of the time, so take my advice with a grain of salt. i have no experience other than this one build but i do have a ton of research time under my belt on how to "hopefully do things the right way". experience trumps all.

I really Appreciate all the adviceyou guys can give me.
When I was using the gto set up. It had the black oring. With the new fbody set up. I used the blue oring. I got it from summit racing. I told them I was installing a fbody pickup. And they told me to use the blue one.
I hope that was right.
Even when installing the blue one. I did have to use a little bit of force to get it to sit right. So I hope a little stupid oring doesnt make me want to shoot myself.

The only way those O-rings go on right is if you lube the daylights out of them.
