    Red face Holley (12-327-11) 110 gph fuel pump inlet and outlet orientation

    I've taken apart the Holley fuel pump by removing the bolts to separate the top from the bottom and I can see that you can rotate the whole bottom to where I need it to be; however, this keeps the inlet and outlet in the same relationship to each other and I need them to be opposites from each other. Can you also rotate the inlet section separately from the outlet?

    I have not yet removed the 2 bolts inside the bottom piece as I don't want to break anything but I'm thinking those must be removed to allow the inlet to orient at a different angle than the outlet. Can I do that?

    Thank You, Gary

    I don't have a definitive answer, because I'm not carbureted and I've never used that fuel pump.
    However, the picture shows two gaskets, so the bottom section must be rotatable.
    But since there's only two bolts for the bottom section, it may only rotate 180°.
    May God's grace bless you in the Lord Jesus Christ.
