Slightly different EFI dual tank question

[Nick_R_23]

I’d like this to be a drop in deal without any modifications to the tanks or necks, was mostly what I was shooting for. Yeah, the Holley units look a bit pricey, but TBI tanks are more expensive than the regular tanks, and by the time I buy sending units, replacement pumps, and void the warranty by modifying them, I’m pretty close to the cost of the Holley units anyway. Plus, they come with the Hydramat and are returnless (internal regulated) and will work great with the newer single feed line rails.
