A few pictures of my M931A0 fuel selector valve rebuild..... 23mm 6-point wrench I made myself to remove the extremely tight big fuel lines from the valve (worked like a charm on a previously-beat fitting) ** All bead blasting was done with pipe plugs in place & the inside valve parts removed **

With 4 big batteries between the load & your alternator should have prevented that. I agree, it would have happened anyway.

Well??

I removed the fuel selector valve, lines a little bit dirty but nothing major. - Fuel selector to fuel filter line = Clear blowing both directions. - LH tank feed hose to selector valve = Pressurize tank, no fuel flow to valve, vent & return line vent air slowly. (Blow back from valve toward...

Does anybody have a wiring schematic for the M939 Protective Control Box? I design power distribution systems for heavy equipment & would like to know exactly what is going on inside that box without gutting mine, just in case I need to replace one or somebody else needs a replacement /...

You are right, I will make the majority of my effort pressurizing the fuel tank & pushing the obstruction forward away from the tank. I drove the truck 650 miles up from Texas & it never gave me a hassle. Filled & drained both tanks twice during the trip. I guess I just lucked out it didn't...

Thanks wheelspinner, I will shoot it down the stack then. How many engine rotations does it take to get to the engine? Yes, it is a fuel delivery problem. The pump is pulling hard, the fuel filter is clean, the line between the two flows 100%. It has to be a clog up in or around the fuel tank...

I emailed the Kansas Highway Patrol, Kansas Dept. of Revenue Driver's License Dept, & Kansas Dept. of Revenue Commercial License Dept. & ALL THREE said that my M931 is not considered a commercial vehicle & I do not have to have a CDL to drive it. 1) I'm not making money with it 2) It weighs...

The fuel tank selector switch would stop ALL fuel flow through the valve, even pressurizing the fuel tanks & trying to blow it through? I have to get me some of those ether cans, getting real tired of the 5-ton boogie :)

How much lift would the box need to clear the tires? Container locks would be great.

Has anyone ever tried mounting a 10-foot CONEX box on the back of an M931? Remove the 5th wheel & bolt down a CONEX box right on the frame. I've got this idea & wondering if anyone has ever tried it.

What kind of cab is that?

So you just fire it down the tall air intake stack?

Can't open it, format issue.

Agree, I need block heaters bad. Both trucks are in extension cord range so yeah, no doubt. I'm gonna have to disconnect the batteries so I can charge them 12 volt as I don't have a 24V charger.
