    The Name Freightliner opposed to White Frtlnr started in late 1977 with the 1978 model year., due to the removal of the White dealership contract due to White Motor going belly up...  I do Not know exactly when the Powerliner came out???

    According to Freightliner, the Powerliner came out in 1973.

  2. The check valves are in the lift pump; if you replaced the whole pump that would fix them. My hand primer pump was bad, causing loss of prime but maybe you already replaced it. I found my leak by removing the lines at the fuel tank, plugging them off, and putting 10 psi air into them...fuel started seeping out of the primer so that showed where the problem was.

    You were lucky I went to two different injection repair shops and called all over the place and I found no help on my old 673 pump and injectors. I finally tracked down Keven All and I bought good parts from him. Your truck is looking very good.

    Thank you! Yeah, I was actually surprised to find this shop...a couple of people I know recommended them. It's Purrformance Diesel in Fredericktown Ohio.

    Does anyone know why GM still makes GMC / Chevy  same truck different trim !  Volvo/Mack Same truck Different Cab and hood! 

    Marketing strategies I guess! Its been going on for years firebird ,Camaro , chevlle/ boulmont   just to name a few!

    I think you're right about the marketing strategies--GMC advertises more of a "professional" angle, Chevy more like a personal truck. Pontiac aimed more toward comfort, Chevy the more basic cars. But as you say, same vehicle, different image.

    We used to joke about the non-turbo 673s in the B-61s we had.  Seems they would run about as fast downhill as they would uphill.  Not very.

    I read online a while back that a guy drove a 673 duplex back in the day, he said you needed all 10 gears because a toothpick would pull the thing down!

    If you just sit the same belt in each groove and check how much it protrudes from the groove I think would give a good indication if the pulley is badly worn I would of thought, totall open to correction

    The belts sit down into the sheaves on the WP pulley, the pulley is definitely worn. Anybody know a part number or where I can get a new pulley? I will definitely try to get a matched pair of belts--I've seen those in the past.

    Congrats on the first start!

    Didn't you bother the injection lines so they kept fuel in the injectors? Looked like pretty easy start for newly assembled fuel system.

    I primed it before starting...had to fill the fuel filter and pour fuel in the inlet line before the primer would pick it up. I'll have to check out the valves.

    Old belts can definitely cause "flutter".  So can off-center, bent or unevenly-worn pulleys (sheaves).

    I put new belts on but the WP pulley is pretty worn...that may be the issue.
