Why not just use a universal in-line fuel filter with some rubber fuel line attached to each end and install it with hose clamps? It’ll basically do the same thing without making you replace the fuel lines and dropping the tank. Depending on the size of the filter, you might need to cut a bit off each side of the fuel line with a small pipe/tube cutter so that the universal filter will fit in there, but that’s what I’d do (especially given the age of the car.)
