Carter stock fuel pump to Edelbrock carb

The fitting goes into the carb in place of the hose barb. Did your old line route around the air conditioner? I know my air conditioner is in a different place than stock, so a stock line needs some bending to get around the compressor.

Years and years ago, when my 73 Duster was stock, it only had a single line running from the fuel pump to, what was then, the single barrel holley since the fuel filter was in the pump. At some point that original line was cut to add in an external fuel filter when the fuel pump was changed. You might be able to cut your original line and use a line like in the picture I posted and then connect the two lines, similar to how the factory did it, with the fuel filter and rubber hose.

Another option would be to stick a 5/16" inverted flare to 5/16" hose barb fitting (I bought one at AutoZone not too long ago) at the pump and then run a rubber hose up towards your carburetor.

Edit: yeah, what Rusty said. Just be careful not to kink the line.
