Oil pick up tube and o-ring

[rdezs]

Just a reminder to the vast numbers of us that will be looking at doing their pick up tube o-ring. Note the pick up tube using two bolts instead of the OEM one bolt. (All LS oil pumps have two threaded bolt holes to use) Below will be the link for the girdle that overlaps the flange on the OEM pickup tube and comes with the two bolts of the proper length. The little bit of red stuff you see in the picture is a dab of red high temp grease to assist in sliding the o-ring into the recess. I also use blue loctite on the bolts. Pick up tube is OEM general motors, they have them on AC Delco's presents at Amazon, and they come with the red o-ring.

Wow, I forgot the picture:

Guessing this helps the tube seal into the pump?

While I've never heard of one of these pickup tubes falling out of the pump.... It just makes sense to have two bolts, one on each side, applying equal pressure....vs just one bolt, applying unequal pressure.

And it seems obvious the original design of the LS engine was to use two bolts. Every oil pump is drilled tapped with two bolt holes.

I would bet money it's one of those situations where only using one bolt, literally saved GM several million dollars over the last 25 odd years....
