  1. ADDING TRANSMISSION FLUID IN FUEL TANK

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Hi Folks I've got what might be a really dumb question. I've been told by several diesel mechanics that I should add 1 qt. of transmission fluid to my fuel tank periodically as this would help to lube the injection pump and clean also.

    99 & up 7.3L Power Stroke Engine & Drivetrain
    I hate messing with fuse boxes. I used the hot wire from throttle position switch. Only thing is I'm not sure if it's a full 12v. Anyone know? I don't have time to crawl under the truck and check. What's a good source to use? Thanks, Steve
