Mechanical fuel pumps

Yes, I was running out of fuel. Upon looking into the issue, the secondary float had dropped down to about to half way down from the sight plug. I set it, and jetted it up 2 sizes on the secondaries. HUGE difference! I'm still getting the car dialed in, with it having on a little over a hunderd miles on it since the rebuild. I thought it was the pump since everything was new and I used a stock pump. Thanks for the replies!
