Does anyone know anything about their being two screws to tweek with on these pumps cause when I turned it up my buddy asked me if I turned up both screws and my truck doesn't blow anywhere near the amount his does and we both have the same truck. 85 f250 6.9 non turbo

 

One is a set screw.



BTW, anyone wanna buy an '87 F-250 with a Banks turboed, factory installed '88 7.3? 5 speed 2 WD, body and bed both rough. Needs lift pump and exhaust work, but it runs just fine.

 

Any idea where that would be located and how to do it?

 

A set screw holds the screw you're adjusting in place. Look around in the photos, there are a lot of step by steps on this.

 

Still can't find anything on this dam set screw

 

Have your buddy show you.

 

He wouldn't show me. That's y I'm on here.

 

Well, I'm sure as **** not driving over there.

 

Iisaw something on a screw in the inlet it u take the mainline to the pump off

 

does anyone know how i can turn my 1988 7.3 ford up so it gets more power and rolls some more coal. and does turning it up get better or worse mpg than before,
