aem regulator. which oriface for 255lph and 440cc?
Just got my AEM regulator, and it says that the different orifaces are used to match fuel pump output for bigger pumps. Which should i use for a 255 walbro intank with 440cc dsm injectors.. .100", .150", or the .200". I dont know if i should use the smallest one or the middle size.

You can use teh smallest one, but when you back off the throttle you may have some pressure spikes I would suggest just to open it up and run the .2 orifice and than you won't have to worry. Remember after you change it check fuel pressure again.

use the middle one, the 255 pump will be too much for the smaller one and you will eventually have probs.i had random missifres becuase of it
