So I am now thinking it is the transfer pump.

I checked all ECM circuit breakers and I have good power all around.

When I look at the fuel delivery pressure reading on the VMS display while cranking, it's reading zero.

I see fuel come out at the secondary when I crank, but it's possible that it's just not enough pressure for the ECM to run the injectors.

If I had a way to put 20psi or so of fuel to the inlet side of the secondary I could confirm this. My last test involved filling the bowl on the Davco and leaving the upper cap loose while I cranked. There's enough fuel in that bowl to get the engine running and yet it is not firing. I see the fuel level in the bowl lowering, but very slowly; the bowl holds maybe a quart, and in perhaps 20 seconds of cranking about half of that has disappeared, probably right back to the tank via the return.

BTW, I have no way to put air pressure to the tank -- too many openings. But, really, this problem can not be between the tank and the Davco -- there's already enough fuel sitting in that Davco to run the engine. If there was an obstruction or an air leak between the Davco and the tank, it should run fine until the Davco empties, and then and only then should it quit. That's not what's happening here.

Anyone have a line on a rebuilt fuel pump for an 8V92?

The HT740 that was installed behind my Cat 3406B is what they call a soft shift. The way it shifts is-1st gear is all torque converter, then to 2nd still in torque converter, then the torque converter locks up in 2nd. When it shifts to 3rd the torque converter unlocks during shifting then locks up again once it is in 3rd. Does the same from 3rd to 4th. I also have a manual switch to lock up the torque converter if I want continuous lockup from 1st. It shifts very smoothly. If your transmission is shifting at too low an RPM, maybe a simple adjustment on the throttle modulator is all that's needed. The modulator should be in full open position at full throttle. Good Luck, TomC

Could you pull air line off and drop 2or3 drops of air tool oil in it/or line then reconnect? I have done this in other parts of air system with good results. I agree it sure functioned until  it sit for awhile.

In honor of Memorial Day, I wonder how many veterans there are among the bus conversion fans, and whether that military service had any connection to the attraction of buses? I served in the U.S. Army for six years, having served in Korea and Vietnam. The trip I made from Albany, New York to Fort Dix, New Jersey after I was inducted in 1965, was in a Trailways Model 01 Silvereagle, and a Short Line GMC 4104. Prior to that, I was enthralled by rides on GMC Scenicruiser's, that I thought were very cool and exciting. In Vietnam, I was amazed at how tough the Japanese Isuzu buses were that were used to shuttle troops around near the big bases. After I got back to the U.S., I crossed the country several times in buses, and I was always happy to hear the wonderful sound of the Detroit Diesels. Bus travel was a more viable option then with both Trailways and Greyhound operating, and you got to see more of the country close up. I used to sit where I could see the driver shifting, and I saw the differences in double-clutching skills. A real good driver could go up and down through the pattern without any grinding, it was a skillful art. Some of the drivers wore leather gloves and took obvious pride in their performance. I was hooked, the rest is history.

I wondering how long it would be until a truck or high vehicle ends up in the cars-only lanes underneath.   Trucks hitting low bridges is one thing, but being squashed by moving bridges is somewhat unusual.

With traffic congestion as it is in China, how long until they have to have a second wider and higher one to straddle all the other gridlocked straddle buses below?
