I’d be interested to read of personal experiences in the use of a funnel diesel fuel filter such as this one produced by Racor/Parker:

Racor Fuel Filter Funnel RFF8C (9 LPM / 50 Micron)

- are these things in widespread use?
- do they effectively filter out dirt and water?
- is the filter element replaceable? If not what is filter funnel longevity before replacing?
- do they slow down refuelling so much as to be a nuisance?
- is the use of a filter received negatively by the fuel stations?
- how do you dispose of the crud that presumably appears in the funnel? Can it be tipped out in to the bin?
- have users found that much crud is evident in fuel supplied from marinas?
- do users consider the cost/effort/hassle worthwhile?

thanks for any responses.

Looks similar to the Mr Funnel equivalents (come in different sizes, none cheap) - Mr Funnel Unisex's F3NCY Portable Fuel Filter, Black, Medium: Amazon.co.uk: Sports & Outdoors

Used for first time a few days ago. Useful funnel, but what was not made clear is that the only way it can filter out water is having the filter higher than the base of the funnel. Hence if no water (99.9% of fills) you end up with an amount of diesel in the bottom which needs to be disposed of (and not by tipping into the tank, or waste of filtering).
Not easy to dispose of. I used some “diesel nappy” and binned that, but hardly eco friendly
 
I've got one, never caught anything but that doesn't prove anything.
Stopped using it as there was always a cupful of clean diesel left at the bottom of the funnel.
How do you deal with this waste? Put it in the tank? Put it back in the can? Save it up?

Just add some water, brings the diesel up to the filter level and stops the water going through.

Brilliant filters I've stopped all sorts of crud from going in the tank.

I use one and if you are near, you could see it in action tomorrow. Good for filling from cans and the residue is just put back in the can. I’m careful about water in the cans to start with.
 
Another happy Mr Funnel user here. I generally find the sump is totally clear and I pour that back in to the jerry can.
Mine is up for replacement now, it's getting very slow. I don't know if it was ever fast enough to keep up with a fuel pump, but seeing as I never use one, that's never bothered me.
 
I have one, it's in the back of the junk locker, it took ages for the fuel to work it's way through the filter, and as others have said there is always a bit of diesel left at the bottom. I just dose up with marine 16 seems to work.
 
I've got an yellow version of the Mr Funnel. Mainly use it when getting fuel from fuel barges and when transferring fuel. The small amount left in the bottom is tipped into the tank if it is 'clean'. If it is dirty, being petrol I just leave the funnel in the sun and it soon evaporates and then a bit of paper towel to remove the muck. I do think though that fuel outlets have improved considerably over the years in supplying clean fuel.
 
We religiously use a Mr Funnel filter. The fill rate is just acceptable providing the diesel is not "foaming" out of the nozzle. We have large tanks so can usually pick times when a fuel dock is less busy, which helps.

I once dropped the funnel in the water and it remarkable how the filter mesh will not allow water to pass.

It will also filter out any crud. Debris can be easily seen and the best policy is to buy fuel elsewhere if this is present to any significant degree.

We keep the diesel left in the bottom of the funnel (and any drained from the bottom of our primary filters or tank) to use in our Reflex heater. It does not mind dirty fuel, or water.

Yes, I think potentially great BUT do be aware that even with the largest, which I have, it no where needs keeps up with a the typical rate of a diesel pump. Therefore not a problem if your tanks arent too large or you are happy to take a long time to fill, but it can be seriously painful.

What I know do is funnel the first bit through, and maybe check again half way. I would rather use throughtout BUT IT IS JUST TOO SLOW.
 
I have not measured it, but on a typical pump I would say I am back to a 1/4 or less of full throttle. It was so bad I sent it back as faulty and they replaced. Unfortunatley the replacement was no different. I will be interested to hear how you find it please>
 
We have a Mr Funnel and use it all the time. Very handy and worth doing if using fuel cans as they do contain dirt, paint flakes, and condensation the funnel strips it all out. The bit at the bottom we tip into a 250ml plastic bottle and pour that in the funnel at the next fill up so there is no waste and we have never had water in the diesel.

Small amounts of diesel can probably go in the used oil tank. The recycling process recovers diesel as a by product (chemical engineer--I have designed and built large recycling plants). It does not matter if there is a small amount of water or dirt in the diesel. Just save it up with your used oil.

Mixing thinners (depending on the sort) and petrol with used oil is probably illegal. These are flammable liquids and thus hazardous waste.

But really, if you are getting dirt of water in the diesel, there is something very wrong with how you are storing it. For example, folks often blame this on the staion, but this does not happen with cars and trucks, so take a close look at the cans and your tank. Are they rusty? Replace them. Is the vent not closed (there is no way they can gather condensate if it is)? Is the deck fill tight and have you replaced the o-ring? Does the vent have a sufficient high loop? Consider a silica gel or carbon vent filter. Dirt and water do not self-generate.
