I always used a garden sprayer too and it works. But the 6v92 has been a pain to reprime...I've done it half a dozen times now so I can attest to that. Hoping Shanks makes it...sean, take a video of the bus running...and someone stepping on the throttle...just curious to see how its behaving..

Just read all the history on this post. I too am glad it's running. The mental stress of feeling like you don't have any options is not nice.
If you don't already have a place lined up to stay in Spokane, your welcome here. I'm just off of I90 in Greenacres - easy on and off the freeway. Have a level spot with water and power.  Look at my profile and email me if your interested. If you have problems along the way getting here I could probably get out of work to come see what I can do. Worked on detroits in the 80's - still remember a fair amount.  No reason it shouldn't keep running with only a weak cylinder or two. Just make sure the oil and water stay full. Good Luck.

this sounds like maybe one cylinder has a ring problem and one is over fueling/blown tip ?

That sure sounds familiar.  It was a $4,000 new cylinder for our 8v71 but she was fine after that.

So glad to hear this, and really wondering at how hard that thing was to prime.  I guess I really have never had to prime one before, I just installed the little in-line electric pump and I just turn it on, run it till it changes tone and sounds like it has pressure, and start the engine.  $50 for the pump is sounding like a bit of a deal now...

Some things I learned -

1.  Clifford's spot on. Quote for the rebuild outside the shop (Interstate Power Systems in Billings) was 28k and the RnR would be 5k.  33k total.

2.  Put your priming pump on the secondary filter.  This was part of the issue we had.  Putting constant pressure on the secondary filter kept the engine going until it primed.  The pump hooked up to the primary filter did nothing to keep the engine running.  (Correct me if I am wrong or if this indicates an issue with my engine)

3.  The kids are getting a better education on this bus journey than they could get at any public school or college.

4.  Four is better than two :)  

5. Bus nuts are freaking awesome.  You guys seriously are the best community of people I've ever had the chance to interact with.  Thank you guys for all your help through this.

PS -  I'm off to the bus to drive to Spokane.  If anyone is driving 90 between Missoula and Spokane or back today, keep an eye out for us.  Will be in the right lane going slow...

Install a flo/thru inline pump before both filters nothing fancy with the all the bypass valves and piping they prime in a few minutes

Get a 380 Fuel Pro. You will be glad you did.  Can get cheap at truck wrecking yards.

Clifford, do you have a part number / manufacturer that would work well on my Series 50?  I have the two filter OEM setup.

   I purchased an inline 24 volt fuel pump that I am planning to install between the primary and secondary filters since the pump mfgs. want the incoming fuel to be filtered to protect pump. Since it won't provide restriction when off, I'll install a switch with pilot light in engine compartment.

Chessie, I don't think it will pull fuel through the fuel strainer (the first filter before the bus fuel pump) to prime, the filter is just too big.  I run mine in-line before both filters, you don't need a filter on it even though they say you do.
