I thought I'd start a new topic on this since its not really related to the last.

Has anyone, besides KTA, installed the 14mm H&R themselves at home? If so can you give me some insight into how difficult and involved is it? Is this as simple as unbolting the head from the pump and installing the 14mm, or do you have to tear the entire pump down to do it? I know this may be a silly question to those who know, but I and many others have no idea. I've taken the pump off and replaced leaking seals, installed many gov springs, and done simple work on them. But never removed inner parts and torn one down.

We have the same thread here........

I pretty sure he means the actual setup of the 14mm head itself.

 

I installed my own. It is kind of tricky to get the controll collar, springs for the fulcrum lever, and everything else to line up going back together. An extra set up hands was nice.

You don't have to completely disassemble it. I pulled out the gov. lever and pulled it off the back. Getting it all back together is the trick.

Now the bad news. We got too greedy too soon on the RPM and siezed the thing on our first pull. I was bummed. They do really run good though. Unbeleivable throttle response. The failure was from not enough break in time and too much rpm. We did not have super high fuel pressure either. Live and learn. I will try another one sometime.

 

I had no idea there was break in time for the pump heads. I would have swapped it and gone straight to the track. LOL

I may call KTA and see if I can send him my pump, rockentech 14mm H&R, and reseal kit. Not many people I trust to work on my truck, but he has a great reputation so I'll go with that.

For the time being I plan to stick with the DDP4's (55lpm) injectors and 14mm H&R. I should still gain 70-100whp correct? From there I will see where my power and track times are to decide on custom injectors.

Thanks for all the help guys.....
