Priming Diesel after filter change in an OM366LA

#16
Not sure if this is done in the trucking world but on the boat I installed a vacuum gauge after the filters. It has a sweep arm that stays with the highest reading so when I do an engine check I can see if the filter needs replacing. Better than just replacing the filter on a schedule and safer to boot. Racor offers this as an add on for the marine filters.

I've done some fancy plumbing so that I can transfer fuel between the two tanks through the filters. Ive picked up a tank or two of bad fuel and have saved a fair bit by filtering the 160 odd litres of fuel through the filters which cost me $5 a shot - I carry six of them and a couple of the glass bowls as well just in case. I tend to only change the filters when I notice performance drop on the hills, and I can start the electric pumps to push a bit more fuel through if I need to, but it doens't take long to change the filters. I would recommend it for anyone doing any remove traveling.

The other thing I have if I suspect the fuel is dodgy if a water separating funnel - it works great and the look on the servo owners face when you hand him back all the water out his diesel tanks is worth it :) I have the highflow version and it can handle the normal flow rate of a servo fuel pump.

Hey Iain, what you describe sounds very close to what I did on the boat. I have 2 separate Racors with valves to switch from one to the other. If the engine starts to stumble I quickly swap to the other filter while the engine is running. I also have a "polishing" pump that can either just recirculate or transfer the diesel from one tank to the other. Works very well. We also pre-filter using the same filters you are using. One thing to caution people with those filters though is the "water block" wears out with use. The company recommends putting water in them every now and then to check if it is still working. In Asia we got fuel at times that looked a bit like coffee...

One thing I'm sure everyone does is fill up at the end of the day wherever possible?

AFAIK since the recirculated diesel ends up warming the tank and contents, if you leave it to cool when empty you get the condensation out of the air collecting on the metal sides and running down. Over time that builds up.

Filling up at the end of a run before parking up would be with possibly cooler diesel, and then there will be less air in there, and so less condensation.

:)

Another good thought about the condensation, thanks for that idea. We just last evening completed our run with our "new" truck from Florida to Vermont. All went reasonably well except for the fact that the existing fuel tank had junk in it. Had to replace/clean the filters twice in parking areas on the drive up. Bit of a pain, but now we are here I am going to begin the build and one part of that is the upgrade of the fuel system.
