Default Y block or T'd hoses to supply rails?

I was planning a fuel line from fuel cell, into a Y block. Then two hoses out of Y block going to each rail.

It was suggested to me to use a T fitting closer to the rails to clean up some of the routing (2 hoses going to the rails) from the side of engine compartment.

If I do so is there a significant pressure difference? What's the norm for a boosted application?

I used a Y-block and 45-degree AN fittings on my
plumbing, just because it looked cool. I doubt it'd
have any effect at my power level, if I used square
stuff instead.

Thanks.

Yeah, I think I'll be pushing 900bhp so I am a little worried what using a T vs. a Y might do. I'd rather use the T because it's less hose to run and less fittings.

DO NOT USE A T FITTING. Always use radius hose fittings on the supply side of the fuel system. Y-block, it may not look cleaner but it is the best route.

As far as the less fittings, I like the y-blocks that already have the ports built on like these:

Hmmm.

So would it be better to use a Y fitting closer to the rails, or a Y block mounted on the firewall and running longer lines (1.5 ft) to each rail?

Be careful about mounting fuel stuff on the firewall. NHRA doesnt like it when you do that.

If I went with a Y fitting (per pic below) I guess it will just sit suspended?
