Am fitting an sc14 supercharger to my 4y-c 2.2l toyota hilux at the moment (blow through)

am having alot of trouble with my carb and fuel pump.
bought a cheap ecco fuel pump and a malpassi rising rate reg.
pump cant supply enough fuel, any ideas on a better hopefully reasonably cheap fuel pump. that will supply at least the 12.5psi the charger will do

am trying to use stock carb, havent yet boxed it but will no doubt have to, at present i get 3psi boost for about 5 sec then it runs out of juice. ideas??

am running 2 bosch bypass valves.

want to keep system blow though and try to keep stock carb or use weber 32/36 dgv or one of the 34 adm's off falcons (would falcon one work ok) wanted to try and get by without the box (room and lotsa pollutuion gear issues).

will try and post some pics if they work.

I am new to this forum and to supercharging so any help would be greatly appreciated.
