1.2 cst Injector Pumps and turbo

[welpro222]

I have purchased a Injector pump recently that I intent to install on my 6.2 with a bank turbo kit. It is the DB2829-4523 23500415 1986-89 HMMWV (Military) - 1.2 cSt C/K.

My question is because this is a (artic Pump) rated for thin fuels, will the pumps timing be different if using regular diesel? Also how much should I turn up the fuel rate for my turbo? 1/8 or 1/4 turn. I was thinking 1/8 turn would be a good place to start, but I would like to hear from people who have installed the Banks turbo kit.

I cant say for sure about the functionality of the cold weather pump but I'm thinking that it will be fine running the regular blend fuel through it. I doubt the timing would be any different though.
I have a banks sidewinder on my truck and I turned it up a quarter turn, just like the tech sheet states. I'd be cocerned with running it to lean if you only go an 1/8 of a turn.

I was thinking that too, but everywhere I have read says you cannot run a diesel too lean. Here is a quote from the banks install instructions:

It is important to realize that diesels, unlike gasoline
engines, run cooler with additional air. It is impossible
to run a diesel too “lean.” Exhaust gas temperature
rises as more fuel is added.

Its a 50/50 I guess? Run it 1/8 turn and it will be fine or I may need to turn it up, Run it at 1/4 turn and it will be fine or I may need to turn it down if exhaust temps are too high.

So, you need a 1-2" micrometer, compressed air and some tools to accurately measure the roller to roller dimension of the pump. That is the only way to know what the max fuel is set at. Honestly I'd just slap it on and try running it the way it is. The artic pump is only different in that the transfer pump is made with materials that will withstand alternate fuels. Only other suggestion is to buy a brand new quality t-handle long Allen key to use for max fuel adjustment. It actually takes a fair amount of force to turn the screw on the rotor, and you really don't want to contaminate it or damage it.
