Its the felpro kit listed on the paper in the background. I used the black one and it went on good, I just want to be sure I'm using the right one. I read the red one is for a pickup tube that is recessed, not sure on the green one.

IIRC it should be the black one.

This instruction sheet came with my Melling 10295. It is somewhat of a challenging diagram to understand if you don't know what you're looking for, but it helped me.

I also vote for a black o-ring on your application.

Green is truck pickup tube, red looks way too thick, black looks like the winner.

I would not use any of them...
GM had a revision of the O-Ring...
go into a GM Dealership and get the right one... which I believe is a Blueish color now.

whats the difference?

not sure...
but at a minimum, I would go in, and see exactly which one they want you to use instead of asking people to guess from an internet picture.

if the o-ring doesnt seal properly, you will have oil issues
at a minimum, its worth the drive to the dealership to see what the GM recommended part it.
take the ones you have with you.

hmmm, i thought maybe felpro knew what they were doing....

its not supposed to fit loose...its supposed to be hard to get the pickup into the pump...

This is a very crucial seal...it needs to be tight

I used the red fel-pro on my 99, it is thicker, just lubed it with motor oil. The fitment was a little snug, but the pickup tube did fully seat and I have no pressure issues. Believe that part number 72401 is the part I used.

yea it was tight, I had to force it in. I had plenty of lucas assy lube on it too. It had a good positive feel, I'm pretty positive it will work.

I used the orange one. Orange seals came off my 2006 4.8 and 2008 5.3.

Used the red one...I think I had pinched the black one and could not use it...I went to the parts store and picked up that red fel-pro seal after searching post here.
