If you converted that system from a return type system to a returnless using a regulator, you will just fry the pump. Those pumps aren't designed to run that way.
what pump system do you suggest i run?
It's a conversion that really should never have been attempted. It requires a different fuel tank and external fuel pump, preferably the engine mounted factory pump. These modifications aren't even legal to do.
thanks i will run engine mounted mechanical pump.
You need a different tank first.
can i not just pull the pump put back the sender,then put an in line pump and a mechanical on the block.plus the regulator?
No, because the sender will no longer reach the bottom of the tank and you will have an extra line going into it. It also requires a vented tank which is illegal now. You can't just think you are going to "old school" and EPA certified car. The fines start at $2500.
