If you can fill the hole, you can run the oil pressure sendeer on any number of locations. You can get the Z10 adapter fitting and run it off the oil pump. You can also get a GReddy, or similar oil filter block adapter and run it off that. I myself am running without the OEM oil pressure sender. My turbo feed goes directly into the block, in the OEM sender location, and my GReddy oil pressure sender is mounted on the flywall, and fed by 1/8" nylon tubing that connects to the filter block adapter.
