Setting Fuel Pressure

[INTMD8]

Sure, I'm not saying it cannot work, just saying the way I prefer to do it based on my experiences.

Also, I've never tested fuel temps with either setup but I would be curious to know the difference. I think a step down box, or triggering the 2nd pump so total fuel recirculation is reduced would have more effect on fuel temps than regulator position.



With it rear mounted you are not recirculating fuel that has been through the hot rails but you also have much more stagnant fuel in the rail which may or may not have time to reach the same temp.
