I have FiTech system on my '89 Diplomat Police with 410 stroker 360 that has an Eddy Air Gap intake. I was so relieved to have hood clearance to use my factory four barrel air cleaner, as I too like the factory look. I don't think you'll have any issue since I didn't with an air gap and Diplomat hood. I'm using factory linkage too.

I don't have an in-tank pump so can't answer those questions.

Facts are stubborn things.
