MichaelAfter looking at the photos, i believe U have a gravity problem, the lower the tank, tanks, are the harder it will be to pull the fuel into the spray bar. From the photos I would raise the feed tank, which I believe is the small tank, to a higher horizontal position with a height the same as the spray and find away to also raise the big tank to the same height. After U raise them I believe U will need to lean the mixture some because the gravity will not be restricting the fuel going to the carb.
Michael have you tested the tanks. Isolate them and see if it runs on a hopper and only one tank and do you have the large pipe fitting and is it drilled in the right spot on the pipe. I'm thinking your Loosing preasuer somewhere like a line or tank seal or a bent brass line.
Please share pics of the fuel system in the sprint cat. I would still say there is a problem with the tanks in the conquest
