Normally, no.  But I have seen pumps that were assembled wrong (spring out of place) do it.  And some reproductions seem to just
have the wrong spring installed (also causing pressure too high).

Wouldn't hurt to hang a fuel pressure gauge on it (most vacuum test gauges will also read fuel pump pressure); but if the Viton
valves don't help, I'd take Geo's advice and look at ignition next.
