    fuel pump

    not sure which pump you have but a good many of the holley pumps take 3/8 NPT and then there are some that take 1/2" NPT.

    Your asking two diff questions now. A 3/8 brake line will not fit a 3/8 npt, a pipe thread has a tappered thread pitch. Are you asking if you can use 3/8 brake line as the fuel line? Sure, if you attach some sort of 3/8 hose in between or find two 3/8 inverted flare bushings to put in ur pump.

    AN fittings are the tapered seal, streight thread fittings commonly used on the fancy red and blue fittings and anything also commonly reffered to as JIC.
