Oil & Fuel Dk45 won't start after fuel bowl change

TonyI,
Went through a similar thing last week.
My Kubota has a air/bleed valve for 'cracking' the lines.
Ran the battery dead and had to get the Dodge Ram along side it to jump it.
I thought it took longer than it should have to run the air out and the fuel through. Glad you had sucssess with yours.

All of these ways are adequate to do a normal filter change. But, there should be no reason to break the injector lines loose unless you are priming the high pressure side of the system. The only time this should be required is if the engine is ran completely out of fuel, of there is major work done to the engine where the inection pump/injector lines are removed.
Personally, i do not like the idea of pre-filling a fuel filter. With modern diesel injection pressure being increased for emissions compliance, better and better filtraion is required. Pre-filling a fuel filter allows unfiltered fuel on the filtered side of the system.

well, done it for 14 years wthout an issue.

yep.. u can get away with it on older low pressure injection systems..... like I previously stated, with injection pressures being constantly increased on modern diesels, its not a wise practice anymore. Years ago, a diesel fuel filter at 50% efficiency catching 25 micron particles was considered adequate...... Modern diesels won't survive 24 hours with that filter...
Tier 4 is here for off-highway, stationary, and agriculture machinery....
