Peter,

my oil pressure sender is behind the fuel pump sticking out the left side of the block (put a new adaptor in last weekend). May be possible to do a dual sender at that point (mine has fair bit of room around there) .. but then we may have different types of blocks - mine is a 4 bolt with lower water hose coming out to the right of the crank (left/right as viewed from drivers seat).
