    :biggrin_2552:In the past I have always slightly bent the new unit to go into the fuel tank. Can't do that with this new sender, I need to spin the tank. The tank is empty, one band loose. The other band won't budge. As you all know there is very little room to get a long wrench on the nut. Sooo how do you guys get the straps loose on a Pete? Don' want to cut it.

    Have you disconnected the leveling valve rod and used the air bags to raise the cab/sleeper as high as they can go?
     
    mtoo Thanks this.

    Well this sucks, peterbilt gave me the wrong sender. My old one has a female pigtail coming off the unit, the new one has a male plug directly on the top of the unit. You would think after giving peterbilt the serial #, you would get something as simple as a sending unit right.

    That New Years Day project is over. Next project rebuild the air dryer, new cartridge - purge valve and heater. Hope those parts are right. Miss the old AD-9 dryer, not sure I like the AD-IS

    That sending unit replaced the older one. They sell a jumper harness to connect the new sender to the old harness. PN# P92-7180-0650 it's around $14. Just went through this for 26" tank.

    Changing the pigtail must have been a Paccar bright idea. The same scenario exists on a KW. Fortunately my parts guy knew I would need a pigtail.

    I just returned the senders. It was just going to be a New Years Day project and didn't need to be done. The only reason I was doing it was because the right tank doesn't read full, but works from 3/4 on down. Stuff like that bugs me, but no real reason to change them.
