The 89 pump is for fuel injection. It will be WAY too much pressure. The regulator would need to have a return line to the pump to make that pump work. That pump will not allow pressure to be controlled by an external regulator - it would have to have a return line - just like fuel injection works in those trucks. If you got a simple a/m pump, you would not have that issue. If you got a good mechanical pump for a 318 (older modle), you should be ok - as long as that engine has a carb. What carb is it - 2 barrel?
