    He's referring to the six sides of the hexagon nut.

    OK, now I think I have fuel in my oil. The truck as always smelled like gas. I can smell it from 15 ft away. How can I verify whether it's the carb or the fuel pump or should I rebuild the carb AND replace the pump? The truck sat for about 2 years. Lots of stuff under the hood could use a freshening up. It's a mechanical pump. Thanks guys.

    You can remove & inspect the fuel pump for a fuel leak, but you'll probably want to replace it by the time you're finished.

    Thanks. Any suggestions for a replacement? Specs, mechanical, electric? Is it worth going electric?

    Mechanical pumps fill the sump with fuel, replace the pump. Easy enough to replace, or can be as complex as your wallet will allow if upgrading the system. Does the current pump keep up with engine demands? Gary

    I really do not know. What should I shoot for, 5 psi?

    Holley suggests a fuel system pressure of 5-7 psi for most of their carburetors. It's in the carburetor or vehicle manual.
