Default twin pump issues..

I installed a 2nd pump in my tank.. 01 formula.. I followed the "DIY on the cheap" write up, but I think I might be having issues with the pumps uncovering at about 1/2 tank... the car idles good for a large cam, but once its lower than 1/2 tank it will die out, and hates running.. basic "out of fuel" feeling.. So I am pulling the pumps and going to re-check and and tighten stuff down..

my primary questions are..

the small 1/4 nipples on the pumps are for what?
I used teflon fuel safe tape on my fittings(yellow)
I used 5/16 fuel injection hose, and issues there?
I had to mod the bucket to make this work, do I need to just replace the bucket and start over? By mod, I cut it up to make the 2nd pump fit.

thanks in advance, Ill post pictures tomorrow..

if you didnt put anything on the small venturi nipple on the top of the pump you will be spraying fuel at the top of the tank.
