I've been filling filters with both oil and fuel for as long as I can remember and the idea of that ruining engines is rubbish IMHO.I've done it a thousand times and have never had an issue and will do the same with my TDCi,both Land Rover and Ford fill the filters before fitting,I know because I asked.

I am wondering if diesel fuel injector cleaner would be alright to use
to fill up filter after change? ..a fresh 500ml bottle would fill the filter up nicely
and no risk of dirty diesel...??

Not to sure about that, sounds like very strong dose as it not diluted with the other diesel in the tank.

I agree pat, I always have and always will fill my oil and fuel filters to the brim when changing..when I service my Detroit series 60 truck engines I do the same, yet if they run out of fuel, they will not pick up fuel by the same method, I have a garden weed sprayer fitted with a quick coupler, fill It with diesel, pressurize and it will start, have never run my puma 130s out of fuel so not sure how they pick up...every diesel is different. If you get stuck and are really, really desperate...very desperate! Aerostart will kick an unprimmed diesel, though it's a last resort and I wouldn't recommend it, but it works..

The reasons are modern diesels run finer tolerances and higher injection pressures and if there are contaminants in the fuel it does more damage. Yes you are able to get away with it in older mechanical style injection but common rail and electronic unit injectors aren't as forgiving.

I have just come of a course on the Bushmaster that has a Caterpillar engine and CAT specify not to pre fill filters, and for the reasons given.

So by all means keep doing what your doing but don't cry when your engine blows smoke and your injectors need replacing.

Education is not just for kids!

Caterpillar have been saying that for years,every mine site I've worked on specify that ALL filters be pre filled. Pat

The electronic copy of the workshop manual for MY12 does not give directions to pre-fill the filter, instead it directs a re-prime of the system using the 'special tool'.

It does not explicitly state not too either. I would suspect if a dealer is filling filters prior to fitment then there could be grounds for disputes should the fuel system fail and they have adopted this practice as a shortcut. The issue being any damage caused by this procedure will most likely not be evident until after the warranty has expired-the dealer therefore has no incentive to do things right!
