Most Popular Questions

Does this come with a new IPR valve?
View Staff Answer 

The IPR valve is not included with this pump.(Only the 04.5-07 Bostech Ford 6.0L Powerstroke pump)

Do these pumps have the ball bearing style pressure relief removed and modified?
View Staff Answer 
Yes. The older ball style has been modified with a threaded plug. The original design was a bad design as the ball style had a tendency to just fall out of the pump. Bostech been modifying the HPOP123X for 4 years with great success.
