Can anybody tell me the thickness of, what I think is, the oil pump manifold
(black plastic thingie) that mounts under the bracket that holds the primary
fuel injectors rail? I'm not using the oil pump so I need to replace that
thickness with spacers.

Thanks,

I need a picture of that. I thought the oil pump manifold was internal inside the block.

OK I think you mean the apex seal oil metering pump feed tubes?
