The DieselSite ADRB95 is the billet housing version of the Adrenaline high pressure oil pump for 1994-1995 7.3L Powerstroke engines that need the anti-drainback feature. It is a bolt-on, high-volume replacement for a worn factory HPOP that can no longer hold injection control pressure under load, which shows up as long cranks, low power and a P1211 code.

What sets the ADRB95 apart is the housing. DieselSite machines it from billet instead of reusing a factory cast housing, which addresses the weak threads and common leak points of the original casting. Each Adrenaline is flow tested to the same spec before it ships, and it is built to use the later 1996-2003 style IPR valve.

• Billet Housing: Stronger threads and fewer leak points than the factory casting.
• Anti-Drainback Design: Matches early engines, serial number 201680 and before.
• Flow Tested: Every pump is tested to the same flow spec before shipping.
• Injector Support: Stock through 175cc single shot, AC injectors to 200cc and hybrids to 285cc with tuning.
• Uses Later IPR: Built for the 1996-2003 style injection pressure regulator.
