Oil sending unit size (other than 1 1/16?)

The regular deep well socket I used would slide all the way down and touch the top of the valley tray. This is with the tray off the car, not sure if that helps you or not.

My guess is the socket you have is not fully broached, and you are running out of depth.

I know this is a couple of months old, but I just replaced my sensor today. I believe your socket is hitting on the shield sitting right in front of it. I had this same experience an hour ago. Also, I removed the OEM unit with a 12 point 1 1/16” deep socket. I had to use a 6 point to install the new one.

Do you remember what you had to do in order to not hit the shield? I’m running into this issue. I assume I can’t get the right angle on my socket to go over the old sensor because it’s too tight and I’m hitting the shield right in front. Tried for about an hour last night but couldn’t get the socket onto the old sensor to get it off. I’m using a 1-1/16” oil pressure socket. I’m working on my 2012 Suburban LS. Any advice would be appreciated.

My advice would be to remove the intake manifold. First time you do it will take about an hr to hr 1/2 once your experienced it can be removed in 45 minutes. I've tried a few times to swap out the sensor with the manifold in place and couldn't get it done. It's just too tight back there causing gashes on the hands and quite a few Eff Bombs!

Okay, thanks for the reply. Any special tools needed to remove the intake manifold?

Only tool I would consider special is a fuel line disconnect tool which you should have anyway if you're gonna be doing more d.i.y. work. Also should replace the manifold gasket while it's off. Watch a few YouTube videos will help with the details. Also be careful when lifting the manifold off, it could have some oil puddled inside that can leak onto the motor/belt.

Only 10 minutes to pull the intake. If you've never pulled it before, 20 minutes..... And check the valley plate bolts while you're in there. There'll be a few loose.
