Obviously not letting your bus run out of fuel is the best solution. However, a few times while working on the bus the fuel line and filters drained back or ran dry. This of course causes undue stress in refilling the system. After the first time I thought there had to be an easier way to pull the fuel. Here's what I installed and it works like a champ:
On a spare "plugged" outlet on the main fuel filter housing I installed a high quality quarter turn shut off valve. Off the valve I ran a short piece of steal fuel line. On the other end of the fuel line I installed an inexpensive 12v electric fuel pump which is wired to my 12v system (in this case the generator start battery), with switch installed. On the end of the electric fuel pump is another small piece of fuel line with a cap.
The second time I ran the filters/line dry, I simply removed the cap, put an gallon container at the end of the line, flipped the switch and pumped fuel through the system. When the container starts filling, so does the filters. Worked like a champ.
Also works if you need a few gallons of diesel to help out a friend.
I'm sure someone out there has done this before, or something even better, but for at the moment I was pretty impressed with myself and wanted to share.

Another possibility is a fuel container that has the necessary plumbing connections, and the ability to be pressurized slightly.
I used the carbonated beverages pressure tanks in the past, but you could easily use something like those compressed air tanks that are used to seal the bead on tires. Have two sets of outlets. One to set the bead on tires, and one for the road to prime the fuel system. |

Simplest and most fool-proof is to use a 2 gallon plastic agricultural pump/sprayer like you use to kill dandelions. $20 or less. Change the hose to accomodate an easy hookup to a shut off valve at the primary filter. Put some fuel in the jug, screw on the lid and pump a little pressure into it.

Had a trucker tell me that a siphon gun, like used for parts washing, undercoating, hooked to the fuel line, with and active (running) air compressor, will suck fuel through on a detroit line. When the fuel comes out the spray nozzle, the line and filters are full.
But you need a 'donor' air source unless it the stars are properly aligned. I used a 12 volt fuel pump, installed a fuel gauge, Fill at 1/4. God hates a coward, but I can't spend time at the side of the road.

Harbor Freight sells a manual oil transfer pump for less than $10. Mount one in the engine compartment and hook it up in parallel to the fuel pump. |

The maintenance manual for my Grumman with DD 6V92 says to "fill the filters by pouring fresh diesel and screw them back on". Does it work? I have not had the need to do so. |

"Does it work? I have not had the need to do so."
If your replacing the filters as a PM it works fine , because the fuel lines and pump are full of fuel.
If you have run out of fuel and the lines are full of AIR it will take some extra dooing.
Some folks fill the filters and start the engine with an oil spray . WD40 used to work , but Im told to now has no kerosene??
Starting fluid is NOT an option unless the engine is cold and its 0F outside.
A modified sprayer that fills both filters under pressure works , but needs to be carried full at all times , fire danger and space waister.
Pressurizing the fuel tank to 2 or 3 psi works , but could get expensive with an old tank.
MY Way is to use a Mity Vac , a metal pump that is ordinarily used to change brake fluid ever 3 years (as recomended bu most car MFG) .
They can pump pressure as well as suck the fuel into the primary. So most times its a 5 min job to pull two fittings.
Suck on the top of the primary and push the fuel into the top of the secondary (old non spin on setup).
