Good points Fred. Having already done a few, you would be in the know more than I.

Not sure on the pressure. I just remember reading something to the effect that the Toy box worked better with the GM pumps pressures. ??? I can't argue one way or the other.

This is the picture of the FJ kit in question. Unless they modded the GM pump, I don't see any regulators or anything. Would it possibly have an internal modification?

My 250 I-6 for the truck came with a GM pump and bracket, so if I go the Toy box route still, I will need to modify the pump I guess. Would you have a link for the modification parts?

Thanks,
