Itll be years
Ships are piped in such a way, that They can not pump new fuel directly in to the engine , it has to be pumped in to a settling tank, then heated, so ,it can run through the fuel oil purifier , and then in to tank, where fuel oil treatment is added, and you ALWAYS add fuel oil treatment to DFO ALWAYS.
LOL prick
FYG only the wiper blades, but they don't have em for Hendrys truck.
On the LNG fueled vessels There are 2 filter elements on the Pilot oil filter skid ,the pre filter and the final filter, there are 3 pilot oil filter skids on the vessel 1 for the aux DGenerators and 2 for the Mn Engine .
This is the cost for the prefilter element, ( smaller one)
