Mike 1 Report post Posted October 21, 2007 just curious but why would you not want it to run off manifold pressure? Quote Share this post Link to post Share on other sites

Each 1 psi of inlet pressure leads to 1 extra psi of fuel rail pressure. So (guessing a little here), disconnecting the vacuum source should just leave the pressure fixed at the standard rate? Anyways, I've seen the D-Jet one part way down this article used in an aftermarket EFI setup - adjustable, no vacuum: http://www.autospeed.com/cms/A_2637/article.html Edited October 22, 2007 by CamB Quote Share this post Link to post Share on other sites
