Fitting for oil pressure line

[Hawker7]

I bought a new 350 crate motor and went I went to intall the oil pressure line that goes to my stock gauge but found out the connection in the new block is above the oil filter. On my old block the connection was on the top of the block behind the intake manifold and was a different size. Anyone what size fitting I need to run the line down near the filter? I went to NAPA and a few other places and they had no clue. Thanks
