I need some education in fuel pressure and know you guys can help. I run a Tanks inc stock setup with in tank pump - it is the GPA-4 pump 255 Liters pr. hour/69 gallon pr. hour, I run it with a fuel regulator with return line. I am of course worried that the setup can deliver enough fuel. The pump is rated to 630 hp, but I have a stocker motor that don´t put out any more than 450 max. I have read/heard that a fuel regulator with return line is better than a dead head regulator, and therefore I should not worry about the gph delivery. Can you tell me the difference and will the setup I have be enough to support my motor? Thanks.
