i recently put a 2.3t in my 01 ranger just about everything is done except the fuel line(s)???? i just recently found out about the "returnless system" on my truck. do i need to put in a return line or can i just cap off the return on my fuel rail and run an adjustable fuel pressure regulator? and also is there a way to measure the air/fuel ratio without having to buy the wideband o2 sensor? from what i understand the regular o2 sensor sends a 1v variant while a wideband sends a 3v variant, it makes sense to me that i could find out the tolerances and just measure the voltage... anyone agree?
