Proper placement of Oil Switches on V8?

As far as I know, there are two locations to install oil pressure or sending units on Chevy V8s. One is located near the distributor on the block and the second located near the oil filter, recessed to where it is almost impossible to examine for leakage or replacement on some boats (like mine) where fuel tanks extend towards the stern. There is very little room. I can personally attest to an oil switch failing near the 1 filter and leaking almost all engine oil into my bilge. I am installing Sierra three way electrical oil pressure cut-off switches in addition to the oil pressure switches and oil sending units. My engines require electric fuel pumps. My plan is to connect them all to a brass "T" coming out of the top part of the block, connected to a ss 1/8 npt nipple going into block and block- off the oil passages near the oil filters. In the future, all three would be more easier to access. If anyone out there has experienced problems with this idea, please respond. Thx!
