ATX MKIV #9644 Coyote Build Thread (Index #137) - Trickle Charger Port Added

[dbo_texas]

Loving the build quality and documentation thoroughness of your thread, keep it up guy! I'm a little late to the party, but in post #41 you showed a plan on how to route your fuel pressure regulator and return lines. Does the Gen 2 coyote not require a throttle vacuum line to the fuel pressure regulator? I guess what I'm saying is, will 55psi constant fuel pressure be enough for your purposes?

From talking to Mike Forte and Mark Reynolds at Breeze Automotive, for my application and setup I think this will work great and simplify the fuel line routing. The regulator is a LS Corvette style fixed pressure at 58 psi. I have the 190 lph fuel pump hanger, which they say will work fine with the smaller 1/4“ return from the regulator. I guess if you have the larger 255 lph pump you need a different regulator with a larger 3/8" return.

I'm not sure about your question about the throttle vacuum line - I'm gonna need to research that one unless somebody else wants to chime in. I'm sure this is something well documented on the forum and in peoples build threads.
