Remember when I ask this,..I have two less cylinders than you.
I have the book that creators of the mega squirt F/I system published on fuel injection. Inside that book are recommendations for fuel line size based on target HP.
My estimated/targeted WHP is gonna be something in the 350-400 range at 15 -18 P.S.I..
According to "the book",...it says that I need a 43lb injector (at minimum), with the fuel coming to them in a 3/8 line. According to the book, a 3/8 line is capable of fueling 500 HP.
A 3/8" line........... ( Thats -6 for the AN challenged) for up to 500 HP
Now I was planning on 60 pounders for the injectors anyway,..so it looks like I'll be good there,..and I had a external, inline Mallory pump all picked out that has a -6 out,...but it's marginal.

Free Flow Rate:110 gph
Maximum Pressure (psi):65 psi
Inlet Size:-8 AN O-ring
Inlet Quantity:One
Inlet Attachment:Female threads
Outlet Size:-6 AN O-ring
Outlet Quantity:One
Outlet Attachment:Female threads
Quantity:Sold individually.
Notes pumps flows 110 gal/hr free flow @ 14V, 83 gal/hr @ 40 psi @ 14V, 63 gal/hr @ 65 psi @ 14V. Pump pulls 11.6 amps under full load. Includes 15 amp fuse. Pump is submersible.
If I set base fuel pressure at 42.5,..and the regulator increases fuel pressure as boost rises,..and I'm planning on capping boost at 18 p.s.i., then according to everything I'm reading here,..this pump will suffice. I'll only be asking it to go to 60.5 lbs of pressure,..it's rated to 65.
Our buddies at Summit have their own,...uhh,....."version" of the same pump,...and it's rating shows it's flow capacity in pounds per hour at 450.
Free Flow Rate:450 lbs./hr.

So,..given that,..my ((6) 60 lb hr injectors should only demand 360 lbs hr of fuel cumulatively.
I should be OK then?.
Why,..does it matter at this juncture? Why do I need to know today?
It's actually more about the fuel line, than it is the pump,..because after today,..I'll have my version of a Extreme matrix SF connector made,...and once installed,..trying to snake a 3/8 aluminum hard line under that will be almost impossible,..so,...it'll be better if the lines ( supply,...and return) are mounted before I weld those sonsabi tches in there.
