I have one of these and used it to filter 10l of 2 year old diesel. It's flow rate has diminished to almost nothing and all in all I'm pretty disappointed with it given both what it cost and what it promised.
Are there similar experiences out there and is there any way of increasing the flow rate short of driving a screwdriver through it?
 
Bought one a while back and have not used it as did not find it very convenient due to the excess fuel left in the bottom. Would not recommend it..
 
FWIW, mine must have filtered >>5-700 litres (I only fill the tanks with jerrycans) and still goes well.
It's the big model, though the one that has only one filter housing in the middle, not two.

One thing I do not like is the little amount of fuel remaining at the end, but I throw it in a bottle with all types of leftovers (petrol, solvents etc) and use the mixture to clean winches etc., seems very similar to WD40 :)
 
I've got on fine with my Mr Funnel, but after three years it is starting to get slower. The little bit of fuel in the sump can be chucked in with general oily waste (the same as you do when checking your fuel separator).

Sounds like it did its job and is now clogged by long-chain olefines (degenerated cooking oil). I'd assume it's road biodiesel to which you're referring.
If I was GaelForce I'd take a dim view of anyone claiming it's not fit for purpose.
You could see if it's possible to get a new filter?

I imagine you haven't read the claims on the Mr Funnel website?
 
We have three of these Mr Funnel filters.
The filter does need to be cleaned out periodically, I rinse with petrol. The ability of the filter to remove water from fuel is astounding and does work.
I would and do recommend these filters to any one having problems with dirty fuel and or water in the fuel.

I have a proper Racor filter funnel and I found it so slow that i ended up buying a Jabsco diesel transfer pump and fitted a cheep in line filter which was much better.

Any want a Racor filter funnel free to anyone if you can collect.

I have, and it specifies the things it will take out -

"The Mr. Funnel Fuel Filter is specially designed to filter out water, dirt, and debris from most fuels including, gasoline, diesel, heating oil, and kerosene. These harmful contaminants can lead your engine to a loss of efficiency, engine shutdown, or even system failure."

no polymerised olefines mentioned.

Perhaps you're too nice a chap and too gullible for this wicked world...;-)

I am a nice chap, you got that bit right! The Mr Funnel website says "Since the screen is coated with Teflon, nothing sticks to the screen. Just turn it upside down and tap it on the rim." It also says "The funnels are self-cleaning and no replacement parts are needed."

The OP said he filtered 10 litres of diesel, so it shouldn't have blocked. Your speculation that he was filtering something else is just that - speculation.
 
I got her indoors to sew up a chamois like a sock, best filer I ever had when filling, the extended sock or sausage means plenty of surface are to trap any water as well.

Good luck and fair winds.
 
I find the flow through mine varies with the amount of fuel in the funnel. Fil the funnel, it drains OK but as the level reduces, so does the flow. I have used it to remove water and bio contamination from diesel, which it did demonstrably well, and to strain old 2* petrol for my lawnmower (I was surprised how much "rubbish" seems to have accumulated in my petrol can). I'm going to use it on my outboard fuel when it comes off the boat, too.

I was sceptical regarding the Mr Funnel claims so poured the old diesel into a new jerrycan, before pouring the fuel into the boat from the new jerrycan via the filter. Second time around there was no residue in the filter.

I have about 10 litres of petrol contaminated with diesel. This is not easy to dispose of as the local tip stopped me pouring it into the hydrocarbons bank. I've used a couple of cupfulls to start bonfires but at this rate I'll have it for the next twenty years. Sadly I tried using it up in the mower but the carb jets got blocked by the diesel very quickly. I don't know how the filter works. Is it possible that I could use it to sepeate the petrol from the diesel? I've not tried it yet as the cost of getting the carb cleaned and reset is quite frightening.
 
The filter I use looks like one of those. Had it five years, maybe more and put well over 1000l of fuel through it. Worked well when I got it and continues to do so. It is a little slow but it filters so that is expected. There has to be a bit left in the bottom, where else would the contaminants go?
 
Because I had nothing really to lose ( it was scarcely allowing diesel through) I tried cleaning with some thinners. This did improve the flow rate but not enough to overcome my impatience. I think this item will be parked.
Thanks to all who contributed
