I'd use an Edelbrock mechanical pump, it has no return line, and in my opinion is superior to any of the factory style pumps available now.

Yes sir, you are correct. The mechanical pump return will be capped off and the factory return line will be used for the Fitech return line. There should be no reason to have two return lines since the Fitech will be returning all unused or excess fuel itself. The master kit I bought has everything needed hoses, clamps, fittings, pump, efi, 02 sensor and a return line bung for fuel tank if needed. My truck does have dual tanks which both work surprisingly lol. So, hopefully this all falls into place with no big issues.
I'm not completely sure, but when a buddy ran a similar setup (I believe it was FiTech, but an older version) the sump kit had a Holley float valve to keep the sump full of fuel. So if your mechanical pump has a return existing, I would try to keep it vs capping it off. And make sure the sump tank is vented properly, as well.

I run one in my truck. It's an 87 so it already had a return line back to the tank. It works great. I have it mount on the passenger side fender.
