TODAY is a Great Day to visit our Store and order the parts you need for your truck!
Regardless of dual tanks or single tank you still only have one feed line to the pump. One is the output to the carburetor, the other is the return. Some pumps do not have a return.A stock pump is fine and I believe with the Edelbrock you will need to install a fuel pressure regulator as they are generally higher output
May I ask your reasoning for eliminating the return line? Do you understand its purpose?
The OE fuel pump 1/4" return line recycles a small percentage of fuel back into the fuel tank(s). It makes no connection to the carburetor, whatsoever. The augmented flow of fuel through the fuel pump helps cool the pump to prevent vapor lock and stalling. The return line was used most commonly in 3/4- and 1-ton applications to compensate for the additional heat generated by the engine and exhaust due to the increased power demand and extended idling of engines in commercial applications. The return line feature effectively makes the factory pump a high performance item for a 383 stroker. If your motivation simply is to enhance appearance, use -6 AN or -8 AN stainless steel braided hose and fittings to connect the OE pump to the carburetor, strategically anchoring the line with Adele clamps to avoid chafing. Your 1406 carb flows 600 CFM on a naturally aspirated engine; it will never starve for fuel as a result of using an OE pump running a fuel return line.
...I noticed after tuning, that at idle my fuel can't keep up with the demand of the engine....
If you decide to go ahead and install the Edelbrock pump, just cap the 1/4" steel line that runs back to the fuel tank. If the truck experiences vapor lock, you can install a fuel pump with a return line nipple later and reconnect the line.

I live in Denver so vapor lock would be easy to achieve her. Figured out the problem with the fuel upkeep while at idle, turns out my vent line was capped off so it was creating a vacuum.Did you adjust the idle fuel mixture?
