oil pressure gauge issue

[Ken Hayes]

I found this on another forum Shaun.....hope it helps. The guy had the same exact problem as you and this is the info he got.

There's 5 plug's that are in line with the main bearing cap's on the driver's side of the block that can be used.
There's also 1 on the front of the block on the driver's side that's the same galley as the rest.
You can use any of those to install the sender.
And ,Yes ,plug the one's you aren't using.
