hey, i have heard that the old 6.2l chevy, has two fuel screws the one under top cover. and the one in the back inline with the return line outlet fitting. accessed by removing the retrun line???? any info???

 

ttt! Waiting for Captain Save-A-Chevy here hehe

 

I guess your talking about me. Sorry been busy.

The only fuel screw I know of on a db2 pump can be accessed by removing the top cover or the cover on the side of the pump. There is a sticky in the Ford idi section on how to turn up a db2 pump and it works the same way for the Chevys.

 

Yep was reffering to you hehe.
