Well, not me personally but my brother's '76 'B had an aftermarket (who
knows what kind) pump that put out 7.5 PSI to his HIF-4s and he had a world
of trouble with rich running, but not overflow... that I know of.
He had his SU pump rebuilt and it seemed to cure the problem. Until the
rebuild crapped out after about 1000 miles... but that's a new thread.
