There are two different pump lengths, Will. For simplicity, one is short, and one is long. You want the short pump for a Terminator.
All pumps are not created equal. When Ford did the FGT 5.4L engine, they used an improved scroll profile for the FGT water pump to get the 55 GPM flow figure they needed for heat dissipation at 550 FWHP. For the most part, that scroll design never found its way into the production versions of the shorter 4.6L pump, with one exception. That exception was the EMP pump. The 4.6L EMP pump is still available today from Cobra Engineering with that improved scroll design. Here is the link =>

The electric IC pump you see is also an EMP invention, again done exclusively by EMP for the FGT intercooler system. It blows the doors off of all other commercially available intercooler pumps. Here is a graphic comparison of commercially available IC pumps done by Ligenfelter.
That maroon line floating a mile above everyone else is the EMP pump! The EMP pump's stunning difference in pump flow makes a significant difference in intercooler performance.
