If you bleed the system properly before cranking, it isn't much of an issue. maybe a little more so with a 4 cylinder 4000 than a 3 cylinder version; but I would be more concerned with proper methods using the original setup than investigating modifications.

It's a poor decision to move a maintainence question that relates to a specific brand and model of tractor away from that brand's forum.
i'm not at all familiar with that vehicle / fuel system, but if it has any sort of bleed screw you should be able to bleed it with a vacuum pump.
i have a gm with a duramax, and it has a small hand pump built into the fuel filter housing for bleeding after filter replacement, but it's weak on mine. they don't sell any service parts for this assembly, and it's a $650 part to replace the housing, so i needed to find another solution. i just pull the bleeder screw out and hook up a mityvac pump to it.

A universal electric fuel pump can be put into the system.... They have 1/4 inch inlet and outlets... and are operated by a 12v source. You don't want a big pump that moves alot of pressure or volume...
Typically a cheap pump from an auto parts store will usually be 3-5 psi and will work great. You'll need a 12v relay to wire it up correctly... After changing filter, simply turn the keyswitch on and let it prime itself up...
Isnt the 4000 gravity fed anyway?? Seems like yo u could open the bleed screw and jsut let it sit there for a few minutes and it should fill the new filter and push most of the air out... Not sure how long it would take... the electric pump would definitely help that.
