These Mr Funnel are available on Ebay.

I have looked at their website

http://www.mrfunnel.com/Mr._Funnel/Models.html

and note the warning about dissolved water droplets, which I understand. The kit seems to work well - but they would say that wouldn't they ?


Does anyone use one of these funnel pls, and what results ?


I have about 6 x 25 litre plastic cans full of old diesel which has been treated with Grotamar, and I want to use the fuel in the tractor/ quad machine.


The alternative is to set up something along the lines of Laterstarter's philosophy and practice.
 
That's interesting. I have oil-fired central heating and I know there's a lot of crud in the bottom of the tank, so I might be interested in trying to filer the dregs next time it gets near to being empty. However, they don't seem to say what level of filtration they can achieve (e.g. 10 micron or whatever). That makes me a bit suspicious that although it will stop big globules of water (and presumably, relatively big lumps of muck), it might not filter to any particularly great degree.

Yes I have one however filter soon blocks up - supposed to be self cleaning you have to give it a wipe with a dry cloth other wise it takes ages - and frustrates the fuel pump attendant .

And you also have some fuel left in the bottom so you have to decant it into something .
You only find this out at the last minute so next time have a bucket to pour into and then put into an empty plastic water bottle and allow the sediment to drop out then - decant into the tank . And do this with out spilling a drop on the deck - make sure your shoelaces are tied first to minimise tripping risk while holding bottle and filter funnel
 
I've got one, but never actually used it. However, some rain got into the stern locker and filled up the funnel and didn't leak out through the mesh. I thought that was interesting. Up till then I'd been a bit dubious about its water-filtering capabilities.
 
I have one of these, can't remember the size but it is one of the smaller ones as it has a water trap at the bottom. I don't think the larger ones have these. i.e. The filter offtake is quite a bit above the bottom of the funnel. As mentioned earlier, this means that you always have some fuel left with grot, water etc. in it.

When I first bought the funnel I tried a couple of things out of interest.

1) Filtered cloudy fuel (some water mixed in)
Large droplets removed but fuel still looked cloudy. It wasn't as bad as the unfiltered fuel

2) Dribbled water into the funnel when full of fuel
Water collected in bottom of funnel and clean fuel came out through the filter initially. However, once the head of water was much above the filter then some water droplets came through with the fuel.

I still use the funnel and it does work quite well in removing small amounts of water and misc. gunge. But I don't trust it to continue working if the bowl starts to pick up lots of water. To be honest, this hasn't happened in real-life, just in testing.

I usually decant the contaminated fuel into a small can which is re-filtered during next fill. If you are careful this can is almost 100% clean and small amount of water and gunge can be mopped from bottom of filler with tissues. Sounds messy but it isn't too bad in practice.
 
Lot cheaper to use an old pair of tights & an existing funnel. Does the same job as it certainly stops water in both petrol & diesel.

I've got two, one for petrol and one for diesel. They do what it says on the box - certainly keeps the water of your fuel and all the grud from your jerry cans!!

Great bit of kit.

+1 & I would add to get at least the medium sized one not the small one...
 
I have one, I had fuel sitting in my RIB's stainless steel tank for over a year, so thought I had better filter it, the filter worked a treat, it was difficult to make sure I got all the fuel out of the tank so I flushed it with the fuel and filtered it three times until there was no sign of water, I was surprised how much there was because I am careful, it has me convinced it's a good bit of kit.
 
Sorry to turn this into a boaty thread....!!!
I use one for filtering all diesel that goes into my boat diesel tank.The amount of dirt it can intercept is jaw dropping sometimes. if fuel is dirty fuel thoughput does slow down significantly which is understandable with such a fine filter. I usualy wipe gently with a gloved finger which cleans it sufficiently to operate at an acceptable flow rate again.

I started using one when I realised the importance of not allowing crud into your fuel tank in the first place and Yes they are expensive but it is a pretty vital part of your boats systems which one should keep as good as possible.
Money well spent in my opinion.
 
Having looked up the website listed, I thought the following from the FAQ would be of interest in light of some of the posts-

• Test funnel before each use. Add water to funnel to cover bottom 1/3 of filter. Water should not pass through.
• Fuel additives and stabilizers may allow water to pass through filter. Add additives directly to tank.
• If fuel has been shaken (for example, in transport) let it rest several minutes before filtering; otherwise, water in fuel could pass through filter.
• Do not attempt to remove filter from funnel. It is permanent.
• Do not wipe out or clean funnel after use.
