Engine Oil Pressure Sender - Replacement - what I did that may help others

[mmesa005]

My engine oil pressure gauge was pegged at full pressure leading me to expect that oil pressure sender was faulty. After watching a video on Youtube regarding the replacement of the oil pressure sender on a GMC Sierra https://www.youtube.com/watch?v=oO0T1nJdamY I found it was easier to do the following:

1. Using my phone camera I took a video of the area where I knew the oil pressure sender was located. Just to be certain I had identified the correct component.

2. Using a small step ladder I stepped up to tire height and leaned over the fender area near the firewall. Using my right hand I reached in from the left side of the H2 (facing forward) and along the firewall. I was able to disconnect the wire and get the socket on the sender.
3. A 1 1/16" deep socket, universal joint, 2 x 6" extensions were the tools I used.
4. Took about 1 hour to remove and replace the sender taking into account trial and error of finding the right position for my arm to reach behind the engine.

Note: I only have the pdf version of the service manual and it was not helpful in this case.
