I received a 3310 yesterday (used) it appears to have 2 fuel inlets, but on opposite sides. It looks like the same bowl assembly was used at both ends.
The only dual fuel lines I see available have both inlets on the same side.
WTH

The inlets should be on the passenger side. Unless one of your bowls is tapped on both sides for a fuel fitting, with a plug in the other, then you need a different bowl. Mix and match strikes again.
 
Well the only explanation I can think of, you already mentioned. The 3310 is a dual feed carb but of course should have both inlets on the same side. You might can make it work but you would have to make a goofy looking line to go around the carb. I would go back to whoever you bought it from
 
A 3310 Holley has been around since the 60's in various configurations. Both fuel inlets should be on the passenger side of the carb....someone has put a wrong fuel bowl on it...front and rear fuel bowels are different....the front one has a accelerator pump and the rear one doesn't , in its stock configuration.
 
Yup, I got the issue corrected yesterday. By the time my rebuild kit arrives, I will have all the correct parts.
Thanks guys !
 
FYI Holley bowls have fuel level sight holes that are at different heights on the primary and secondary sides. This will influence your fuel level adjustments negatively.
