Hi-
Does any body know if an Add-On oil filter will affect oil pressure readings? I have a 1957 Chevy in line six. The oil pressure line and the large oil filter line share a single opening
at bottom of block. My pressure gauge is reading zero. Copper lines and gauge are clear.
When I disconnect copper line from gauge and run engine: no oil at end of pipe at all.
When I open connector at block, oil drains out steady but slow with engine running.
Tnx for any info.
