I have a 2002 gmc sierra 1500 denali with the lq4, was running 45 psi fuel pressure idling i then changed the regulator and pump and now idles at 50 psi and is sluggish, if i remove the vacuum line on the regulator the pressure rises to 60 like oem spec says and it runs much better like this. My question is can i run the truck without the vacuum line connected? Will it go lean? Can i cap the line off? Definitely idles and pulls better with the line off.

I'm planning on doing a carb conversion on my Sonoma from the crappy tbi setup. I have picked out most of the parts I need but I can't find a good fuel pressure regulator. Since it's tbi the pump only outputs around 13 psi and I only need to step it down to around 7, Would I need a return style regulator when dropping only 6 psi? Or does the stock pump have a pressure release valve to release the excess back pressure from the step down? Any helpful information about the conversion would be nice. I also have Vortec heads on the 95's V6 not the stock pre-vortec heads if that makes any difference. I have everything picked out except the carb and regulator, if anyone has ideas as to which carb and regulator I should choose let me know.
