restoration If you have water and dirt in your fuel read on!

[Diana and Jackie]

Very handy device that does work, took a load of rusty water and dirt from a tank of petrol. Fill it with water and not a drop runs through :-) !

Not really new I think

I can remember Dad having a funnel like that back in the late 60's. Just had a very fine gauze in it

But this one removes water :-) Good link, thanks

That's what the old fine gauze funnels did.

Bought one of these at our local agricultural dealers annual show four or more years ago . I think they said , at the time , that they were developed for the aviation world .

This one removed water. The gauze was so fine it would let fuel through but not water

These type of funnels have been around for years, I remember using one early 70's delivering parrafin.

Normally only needed when fuel has been stored for a long period of time or incorrectly.

Still a very usefull piece of kit and thanks for the link.

My understanding is that the finest gauge gauze will not pass water within kero, DERV, petrol BUT only reliable for a bulk passage that you accept will still contain some small trace of water , after that you need a sedimenter then a final finishing filter prior to a carb or fuel pump. Obviously WW2 era. carb(s) and inject pumps are more tolerant of a bit of water content remaining.

Aux. engines for ships built in the 1950's (such as WW2 era. Rustons) - the final finishing tended to be done with a Alfa-Lavel centrifuge , plenty of water was removed along with magnetic swarf (wtf did it all originate on a 16 year old bilge & settling tank) & other sludge on the plates

Back int day, before winterised disiel these gizmos were essential, that and bury two cans of fuel in the muck heap overnight so you had warm disiel to pour into the tank on a frosty morning. :-D

Gauze water separation - I understand the theory is that all water has surface tension - hence you can see water 'balled' in the base of a container of fuel. Diesel contains wax and this gives a better (stronger) surface tension at the interface of the fluids. If the gauze is sufficiently fine then the surface tension can't burst and thus the gauze holds back the water like a dam, I suppose the lower the head of fuel against the gauze - the better it works.

Thats how I understood it worked
