    What did you do with your GMT400 today...or yesterday....

    Changed the oil on the ‘99 with the new 6.5 Optimizer at 2300 miles since the change at 500 miles. Headed up to Montana this weekend and did not want to go past 3000 on this oil change. Truck is running great.

    New Injection Pump Shelf Life

    Marty, I find that persistence wins the day and you most definitely got it. May God bless this 6.5 Optimizer with a long life.

    Is the roughness or hesitation gone?

    Suction Side Air Leaks

    That’s a good price. What is Flight System’s reputation on reman pumps? I have two cores in the garage and probably should send at least one in for a reman.

    New Injection Pump Shelf Life

    Marty your reman IP worked for me during my brief test runs. At worst it is some sort of seal causing the problem. The hard components should be fine. Do not condemn it.

    4” schedule 4o pipe does not fit schedule 40 4” wye

    There were several words used that I did not know WTF he was talking about. So It’s a two person job.

    4” schedule 4o pipe does not fit schedule 40 4” wye

    The gluing takes 10 minutes. One guy glues and fits the pipes, the other guy uses a plastic dead blow hammer to smash them together.

    4” schedule 4o pipe does not fit schedule 40 4” wye

    If I could get some help with gluing, those pieces would bring the total to 120’+ for this weekend. The remaining portion is another 140’.

    Suction Side Air Leaks

    I went with the AC Delco reman off Amazon for $794 with shipping. Last I looked they were $1,100 and now I can no longer find them.

    It’s SoCal, we’re lucky to see below 32 F every 10 years or so.

    Suction Side Air Leaks

    Circled in red should be your incoming fuel line to the lift pump. The o-ring here was always damaged with advanced age. The other fitting is your return line. I replaced both with AC Delco, which will cost you $200+, but you could just try new o-rings which you can get at Napa for < $10. The...

    Probably the right thing to do.

    P0216 DTC

    Lock that TDCO and call it good. All of my prior air leaks were on the suction side of the lift pump. Just because it’s new, does not mean it’s good. For me is was always a mangled o-ring at the tank sender.

    This ^^^. You need to get the Actual IP timing set to 3.50 or less, then you can set the TDCO.

    4” schedule 4o pipe does not fit schedule 40 4” wye

    OK so here’s the story on the line “can’t stop now because the clothes are bought.” It’s from a song called Urban Struggle by the Vandals. Back in the early 1980s when SoCal punk rock was in its halcyon days, the bands would play at the Cuckoo’s Nest in Costa Mesa, CA. Just a few blocks away was...

    4” schedule 4o pipe does not fit schedule 40 4” wye

    Yeah I overdid it with the 8” Schedule 80, but some of that will be going under driveway on the other side of the property and I wanted the strength there. Probably could have gotten away with less, but could not return once it was bought. As the song goes, can’t stop now as the clothes are bought.
