Fueling & Injection - -8 feed line from Weldon 600A...how much power

What will the -8 line feed? Looking at ~800 to the tires through a nitrous motor... should I step it up to a -10 line or will the -8 be ok? Thanks!

Also, is this an efficient "Y" to split to the rails?

-8 on all 3 sides is what I have right now, if it is an ok "Y" then I will use it. They also make one that is -10 into two -8s if I need to upgrade to the -10 line.

most fuel system diagrams will always have a bigger line before any kind of split. if i were you i'd do the -10 into the y then -8s out to the rails. and then a -12 from the tank/cell to the filter/pump. its always best to supply the filter and pump with more than it can push. thats what builds pressure.

it has -12 from the tank to the first filter... the filter/pump/filter are all connected together with -12 fittings in-between them so I should be fine there. Thanks for the info!

to the top.... still curious about the "Y" part.

-8 feed is plenty for over 1000hp I would use the -8 you have and the Y looks fine to me. You will run out of pump before the line becomes an issue.
