My nitrous install story

Well, got the plate system on my truck last month and gave it a try on the street and found that I had a fuel psi problem as I installed a low pressure cutout set at 5 psi (lerned that lesson with nitrous a long time ago) anyway I thuoght that mabe the 3/8 inch feed line in the tank was to restrictive so I pulled it out and put a 1/2 inch line in place of the 3/8 on the sending unit. I go for a test ride same thing. So I hook up a fuel gauge to see whats going on and find out that my fuel press is at around 5psi till I stomp the throttle then it goes down to 2psi . So Im driving back to the house wondering what the heck is going on and thinking that mabe the holley 110gph pump I (THOUGHT) I installed was going bad. Got home opened the hood and to my suprise no holley pump, just the stock pump. Now I knew I bought the pump so after looking around I found it and installed it. I still have no idea why I didnt put the pump in when I did the motor 2 years ago,any way problems gone . 8psi at idle or wide open and with nos. I have made about 7 passes with the timing way back and incresing a little at a time checking plugs. Last night it went 12.39 @ 111.33 mph plugs look great.
