okay, it is fuel injected, although the remedy for the carb i liked also. i had a problem like this.

fuel injection is a little hairier, as mentioned before:
you need a constant pressure to keep the system operating. you may check fuel cells from stock FI cars to find out what may be suitable for the SPF cell (i have never seen one).

the main principle is that you use a catch tank inside your fuel cell with a volume of about a gallon of fuel. the circulating fuel that runs back into the tank should enter the catch tank first to keep volume aroung the pick-up tube, which obviously should be located in the catch tank as well.

to mount this you need to have access to the inside of the tank. any fuel cell manufacturer like harwood may provide more information.
