I am not aware of any that are available from the aftermarket. If you are replacing the high pressure oil pump on a 2003 model year, make sure you replace not only the pump (3C3Z-9A543-AARM), but you replace the cover (3C3Z-9G805-AA) as well as the discharge tube (3C3Z-9T288-AA). Don't forget the ICP sensor (3C3Z-9F838-EA) and connector too (5C3Z-12224-A) if it hasn't already been done too, at one point. The pump cover comes with a new IPR valve installed already, and prices out at the same or LESS than the IPR valve by itself too. There is also a machined groove underside of it, to eliminate the problem with the discharge tube rubbing against it.
Unfortunately, on 2003 model years, you WILL need to remove the intake manifold entirely, due to the rear crossover, in order to access the pump. You remove the intake manifold with the EGR cooler attached to it on these model years.
