                Don,
        If memory serves me correctly, the pump uses NPSF threads which are     straight and exist only as internal threads.  They can mate with     several external pipe threads but not ANPT used on AN fittings.  An     adapter and O ring is available that mates with the NPSF thread and     provides a tapered internal thread for use with standard AN fittings.      I got my adapters from Sacramento Sky Ranch.  I think it is a Lycoming     part.  I described the installation to the folks at Sacramento Sky     Ranch and they knew what part was needed.          Chris Zavatson
