And this is the info I was trying to find/calculate.For each 10 horse power you need 1 GPH or 2.6 LPH flow
So 200HP would need 2.6 x 20 = 52 LPH
300HP 2.6 x 30 = 78 LPH
500HP 2.6 x 50 = 130 LPH
That's the FLOW the engine needs AT the carb or injectors
Fuel pumps flow rate should be listed with 5/10psi(carb), 30/40psi and 50/60psi as those are the most common pressures used
And at 13.5volt, running vehicle is 13.5volt to 14.5volt, for racing vehicle with no alternator there can be a 12volt flow listed
As pressure goes up the pumps flow rate goes down, it doesn't drop all that much between 30 and 60psi
I think the EFI Rangers all used 90-110 LPH at 40psi, so were fine with 60psi change in 1998, Ranger engines were all well below the 300HP mark, lol
Even a V8 swap would work with stock pump, unless you were modifying the stock 302/5.0l V8
There is no benefit in using a higher flow pump than needed, the fuel line size also matters as well
But it doesn't hurt anything to use a higher flow pump
This is great. I feel much better about this fuel pump. I’m sure this will be the end to my lean running issue.
I’ll be sure to post an update as soon as I get this pump in and data logged
