The 1693 code is not a vp44 related code, but you do need a pusher pump with either needle valve or snubber because glowshift sending units are weak you'll burn it up no time... Run airdog, raptor, or fass pump with drawstraw 2 you won't need to remove the intank pump. Dropping the tank is so simple, I'd advise that route.

Hit up diesel dawgs for the airdog, I just did some business with Luke he's a great guy.

 

I thought the 1693 was a companion code?

I have found if you have a couple buddy's to help it's easier to remove the bed.

I have bought several items from Mighty Diesel and Tony is an awesome guy to deal with as well.

 

Got the fuel electronic fuel pressure gauge in today, finally driving my new truck with a little less fear (still nervous though). Had the sender installed at the bottom of the filter, line out to IP, which was reading 8 at initial startup and runs 10 after topping off fuel with bio additive.

Here is another question. The pressure started fluctuating between 12-14 while idling in gear for a little and during deceleration, is this to be of concern? When I demand power, it's between 6&7 psi. I haven't gotten to the highway yet.

Forgot to mention, it runs smoother and quieter than before. How do I tell if the computer is upgraded on the IP? I also confirmed that the shop did not remove the codes as it will clear with normal operation.
