with the size of the needles/seat s in a demonator carb, it is easy for the electric pumps to override them

you can solve fuel pressure issues temporarily by just turning off the electric pump/s and seeing if it runs better before it runs out of gas

On a dominator you have 2 big accel pumps and a shitty linkage set up for driving--they are like a off/on switch--idle or wide open---no place in between

if this is a driver get a better carb
