Leave it to Edelbrock to not use the flare connection for the fuel pump outlet. Both ports are 3/8 NPT. I have purchased the necessary fittings: outlet: 3/8 male NPT X 3/8 inverted flare inlet: 3/8 male NPT X 3/8 barbed The NPT fittings will only screw in between 2 to 3 turns. I know they don't need to bottom out, but they should go in further than that. Anyone hear of this issue?
