Hey fulla's
starting to piece together a aftermarket fuel system (40L cell holley style fuel reg external pump)
but ive ran into an issue no google search seems to know, what is the standard fuel pump pressure out of the tank? im thinking around 270kpa?

ford ED falcon 4L

90% sure the fuel pump is measured by litres per hour. Stock fuel pressure regulator in the rail is 270 kpa

Hey mate! Sounds like a solid setup you’re putting together. From what I know, the standard fuel pump pressure for the ED Falcon 4L should be around 270 kPa, so you’re on the right track. But it’s always a good idea to double-check, especially with an aftermarket setup. Hopefully, someone here can confirm or share any tips to make sure you get it dialed in perfectly. Good luck with the build!
