Wrong Holley 6109 s feed feed from opposite cornersNo offense to the OP but, something is wrong with that setup. Fuel should be fed from the same side. I have never seen a carb with inlets on opposite corners like that. Looks like they are all SECONDARY bowls. Doesn't the fuel inlets always occur on the same side. A quick google search for "dual carb fuel line" comes up with 100's of them. They all feed from the same side.
The old painted regulator goes perfectly with the mix matched fittings.
Just my opinion.
That just makes them custom heat treated!Ya, looks like 4 primary float bowls, probably because the secondaries are a pia to get a fitting in...at least for me. I wrecked the first one i did. I did mine low buck/back yard, maybe someday i can afford to get mine looking like yours because they look bitchen!

btw, mine were in a fire, they got hot enough to melt one of the bowls off the the bowl screws.
