Bus quit running

If you don't get running to day PM me with a location and I'll come help you out Sunday but we will drive over

Folks:

Thanks again for your help. I'm convinced that my 4107 did indeed lose prime, but sitting for years can do that, I suppose. I guess this is my punishment for ignoring her for so long.

I went to my local N.A.P.A. store (the only act in town) to buy two new fuel filters (AC T-74 and AC T-65) and was told: "Not in stock, not available." As I'm new to this forum, any suggestions on where I might find some? I'm out in the wilds of western Arizona.

just prime the ones you have...
I seriously doubt the filters are that bad. filters show their deterioration under load... not sitting still, even at full throttle...

Cliff:

Just discovered your reply. As I just posted, I have not even been able to locate new filters, although I'm not convinced that they are the problem and suspect, instead, that the old girl simply lost prime. I have not been able to get her started, but I did not pull the filters or do the other suggestions yet as I could not locate replacement filters.

If you won't let me pick you up please at least let me pay for your gas and inconvenience if you're willing to come down here. Tomorrow would be good for me if that would be good for you. You can reach me by cellphone at (928) 255-3705, or I'll call you if you would provide your number. If you're willing to come down, please let me know what I can provide (tools, fuel, etc.) on this end. The stores here (except Walmart) tend to close up shop on Sundays.

That 92 series should have spin on filters Napa 3120 and 3118 not the old type are you sure about those numbers ?

lawful · February 20, 2016, 03:57:55 PM

Cliff:

The engine that the 6V92TA replaced was an 8V71 "318," and the shop that replaced the engine left the original filter set up in there - drains and all. I also had a V730 transmission installed when I bought her (among other things), so it's a bit of a mixed bag of filters back there.

Cliff, since you're driving all the way to help him out, Texas isn't far off your path, can you pull a "scott Crosby" and drive out to the rio grande and help me get a little more juice out of my 6v92? :-)

Scott - Where in Texas name are you?

FWIW ,John only lost prime it just took a few minutes to have him running again.His filters are mounted in a strange place about a foot and 1/2 above the engine at the top of the engine compatment. I think he will just mount a Davco 382 and do away the antique filters.John has a nice 4107 the cleanest I ever saw with a 6v92 and V730,nice car collection along with a nice twin engine air plane

a good guy it was a pleasure meeting him and his wife

You won't have fungus in a fuel tank in AZ Bruce to damn hot for it to survive

As a person in the petroleum industry, I can say this is not true. Microbial growth will happen whenever the Utra Low Sulfur Diesel (ULSD) is exposed to water. When sulfur was still in diesel it would kill the Microbial growths before they started. But sulfur also contributes to Acid rain, so it is a trade off.

If you get diesel with signs of Microbial growth, you need to get a biocide. Those little buggers will eat everything including stainless and cast steel.

Also worth note, with the removal of sulfur diesel now has conductive properties much closer to gas than the older formulas. This means that static electricity can occur as the product moves through certain types of pipes. In 2010 there were 3 incidents of tank drives having vaulted tanks exploding on them while delivering diesel.

rule #1.... attach static ground cable .... ?

Post Script:

Cliff came down to Parker with his delightful wife and got my 4107 running in a matter of minutes. I just wanted to again than him and all of you for your input and help. I've started her up several times since and she runs fine. I plan to install spin-on filters to make things a bit easier in the future, and hope to take the old gal up to Colorado this summer (up and down Wolf Creek Pass, again).

I'm certainly glad I joined this forum and hope that I can be of help to someone, someday.

On another note, I noticed that my air system seems to be working hard to keep the air pressure up. I then noticed that the device next to the brake air reservoir (in a compartment under the driver's seat) has a constant flow of air coming out of the hole in its side. I'm not sure what it is (I suspect that it is some sort of a valve). Should air be coming out the hole at all times?

Have someone listen while you push the e brake down and release the brakes ( make sure you have the wheels choked before you do this. If it stops when you do that your pressure release valve might be in need of rebuilding. Or do you have a picture of the valve in question.
