I would prefer to use a T fitting, it would be a cleaner look and already a small space to fit a Y block.

putting a T fitting where stock and Aux fuel pump meet to go into a single fuel line, then again a T fitting where main line meets fuel rail.

Any issues with doing that?

What are the advantages of a Y block here, smoother flow? etc..

I've seen vendors using a T fittings that connect an aux pump between a quick connect, so essentially doing the same thing, but wanted to confirm.

thanks so much.

Just use whichever fits best,

Any differences will be very small. If you're really that concerned, step up the size of the tee fitting
