A while back the T500 was the go to HPOP. Now, not so much. If you do a bit of searching, you can read the reasons why.
Again, I would only recommend/install in my truck a CNC Fabrication or Bosch HPOPat this time.

I got the Bosch a few months ago for $544 from Diesel Orings. At first seemed a lot more expensive, but after factoring in free shipping both ways (core return), and no tax, it was competitive. And Diesel Orings was great to work with, shipped same day UPS 2 day, and 1 day after they got core back I got the $150 core charge credited to my account. So after replacing the non-service plug which held for a year an a half before rear seal went, no oil leaks! I also got new sleeves for fuel pump even though I re-sleeved it when I removed it for the non service plug repair a year and a half ago, and IPR o-ring kit. #14-008 IPR O-ring Kit 1994.5 - 200314-0081$12.84#7-007 Parker Viton Sleeve Kit7-0071$14.82

That wouldnt be good. I have had my Adrenalin for at least 5 years with no issues. Did they ever tell you what the issues were so I could look out for it?

Gentleman,
Colt is my Son, and is driving my old L99 350. He replaced the pump and hoses last night with cnc pump and hoses. The truck sat for almost 2 weeks before he had time to work on it. Any after all the work we could not get to start. I know it's a common issue so we kept cranking until the batteries almost died. Going to recharge and try again today. Just wondering if we missed something.. the truck builds pressure but as soon as we turn key off it drops to nothing. With my torque pro and obd the ipr which is only about year old was reading 14% hpop pressure when cranking went up to 190. Ipr would go up also. Any advice would be greatly appreciated. We are building pressure so pump should be good?

The PCM needs to see at least 500psi ICP before it will command the injectors to inject fuel. Something is wrong if you are building to 190psi only. Once started, the engine should settle down to between 500 to 600psi at between 10-13% IPR duty cycle at idle. Generally, the lower the IPR Duty Cycle for a given ICP the better.

i just replaced mine with a T500 and it seems to be fine. should it ever fail i may then go with a cnc fab but what led me to the terminator was that Jody at DP tuner and Clay at riffraff still recommended them so it seemed like a pretty legit choice. so far so good.
