What is the stock setting for the fuel pump? I need to figure out how far off it is from stock (it's been turned way up me thinks)

It's on a '93 Cummins

 

WOW..... that is NOT an easy question to answer....eg: how long is a piece of string..

The "stock" settings of a VE are very hard to quantify without the use of a test stand and flow metering.
There is no "setting 1, 2, 3" on these old girls.
You need to explain what you want to accomplish, were you seem to have problems and exactly what you are getting out of the truck now.
This is one reason why gauges are so important... without them it's nearly impossible to make sound recommendations without alot of "eyeball tuning".
