      Right off the bat with that kit you are gonna need a fuel regulator that is boost referenced. I will link parts list below of what you will need, that is the same setup I was gonna run on the vega I was building. there is a good video I will link to about it as well. Road kill guys did a video about it. one thing to note is that they get a good bit of belt slippage. it is a good setup right out of the box and will work on your 350 no problem it is the supporting mods that get you.
      Personally read this it explains about the regulator you need and should let you know why.

      First off you can mod a holley 12-803 regulator to do boost but it is not my first choice, although I have seen it done! This is the cheaper dead head regulator style.

      This one is what some low buck guys are running. There are many others most are return style.

      If you want to stick to a mechanical fuel pump then I would look into this one.

      then it is just a matter of rejetting the carb. I would use a wide band 02 meter for that though. Reading the plugs with a blower is not the best Idea but it does work.

      If you just want bolt and go then I would get a weian 142 blower instead it is a roots and does not require a regulator because the carb does not see the boost so no need to raise fuel pressure to over come boost.still would upgrade fuel pumps to atleast a 110gph even for a roots kit.

      This is amazing. I talked to someone at Vortech about one of their "Bolt On Kits" for my Blazer. What I was looking for was something to add a little "Pep" between Smog Checks. Although not Word For Word, what you said above,(of course without all the additional detail)The guy pretty much unsold me on my idea.

      Okay,lets back up here. Still experiencing issues after the engine ran with the bowls full until they ran dry. I did this twice. The question now is why is the bowls running dry? I cracked the fitting at the carb bowl, it had fuel. I unscrewed it all the way to drain what was there and there was very little gas. If I traced the line back to the regulator and crack the fitting or inlet fitting on the regulator there is fuel there. If I back track to the fuel pump, Holley 130 mechanical, and crack the fitting there, there is fuel there.

      Im at a lost right now why this regulator, which I put a kit in, is throwing a wrench into my plans.

      What am I missing here.

      Here is my fuel pump and regulator.

      If we are talking about one of the little 1" fuel pressure gauges I have never heard of having to "burp" them to make them read properly. Have you tried a "real" fuel pressure gauge just to see if maybe something else is wrong ? Are you checking it with the engine running ? What type of pump ? Carburetor ?
