My truck has the original IP I have purchased a new or rebuilt 44 from Industrial injection it has new electrical. 

 My question is what improvements have they made to these?

there were numerous revisions to make the pump more robust.   Timing piston sleeve made harder, better solder used, improved internal design in the diaphram.  

 

However ain't broken dont fix it.

I have 1693 code and it was diagnosed going out its quit on me and died a few times. 

Wouldn't go over 75 but that was probably the lift pump. 

 Does alot better with the Fass I got rid of the Banks ottomind too replaced it with a Quadzilla xzt I like it alot. In the future I'll probably get the Quad.

The 1693 code itself does not condemn anything. It is telling you there is another code in the other computer.

 

I've actually heard that every time you scan you will get 1693 code just because you're scanning 

Have not seen that with mine.

Sounds like BS lol. 

I'll have to get it re scanned it seems to run good. But I've had the new vp for almost a month waiting.  I love this truck.

Stick it over in that thread for everyone else benefit if you want. Clean truck btw!! 

P1693 code is just a flag. It tells the tech more codes on other module. So if P1693 code is present on the PCM then the other codes are present on the ECM. This also applies visa versa.

 

Industrial injection is a certified Bosch rebuilder. All pumps today are rebuilt there are no new pumps any longer.

 

As for updates @Me78569 is right.
