Default Fuel system set up

Got an S480 5.3 yadda yadda

Setting up my fuel system

I wanted it to be 2 -10 feeds to each pump (AEM 380)
2 -8AN outlet into a -10 Y
-8 Y at the rails
-10 Return

With getting filters and everything to fit in rear of the car the -10 did not work

Was going to mount the pumps along the subframe but the 044 style pumps aren’t the best for pulling fuel that far

So my question is

Can I switch to a Dual -8 Feed and not become an issue?

Fuel will be E85 and the power should be right at 900-950 wheel

Even a single 8AN feed would be fine. That's all I run, with a 6AN return.

Oh maybe I misunderstood. My AEM gets a -10AN off the sump and I've got a Walbro 450 in tank, they come together at an 8AN Y and a single 8AN runs to the rail. 8AN feed to the pumps should work fine.

If you don't mind me asking with all the fittings and such how much do you have in the dual AEM setup? I ask because Holley is making that new dual dominator pump that might be in a similar price range

I feed dual AEM380s with a single -8AN feed. No issues, but I haven't leaned on it at all.

Yeah I can't see with each pump getting their own -8 that it'd be an issue, The pumps in reality are a -10 to -6 so so don't think it'd be an issue with the same size inlet and outlet causing vacuum,

I picked up some 90 degree -8AN filters that I think will fix my issue with space, With the other filters and such by the time you get 2 fittings on each end of -10 stuff you're taking up some space.
