dual fuel
I have a 383 stroker with the dual set up on it fuel is only coming out on the passenger side two ports ( I have your in tank pump)
I have grounded the throttle bodies they are on 2 inch risers ( only way I could get the distributor in it is very tight)
I have insulated the blue wire to the coil and it still does this ( this is in inside the car nothing around it
it is a msd blaster ss coil and a ready to run distributor ( is there a better one that is smaller that you would use)
I do not have it returning the line goes pump to throttle body nothing in between
Just so you understand, this is not Fitech. I started this site on my own to help us all learn.
If I understand correctly, you do not have a return fuel line. You must have a return for the system to work properly.
