Fuel filter losing it's prime

[Northern Bongolow]

the stuff they put in new fuels,both diesel and petrol hates water, and as fuel floats on water, if you have got the dregs from a tank,there is a fair chance you have got the water/fuel mix, this forms a mild gel.the new guide to the industry is to use all fuel supplies in a 6 month period,this includes gas oil for inland marine purposes.all garages selling fuel had to certify that there tanks were free of water some time ago,but the poorer ones are maybe at risk.
the lesson really is only fill up from busy well run sites that have a high turn over of fuels.
its just another way the supermarkets are going to take over the world.

tgp,

would think myself if its quite fine the pump would mash that up?

take it as an engineer you have decided its such low risk ,know not all cars have them.

I have had occasions when the engine would'nt start and removing and cleaning the banjo filter fixed it. So something had reached the banjo filter but not been able to go through it. Not quite sure what that proves tho!!

At the risk of repeating myself....................... The banjo filter is there to pick up pieces of fibres from a new fuel filter - the cheaper the filter, the more fibres it'll send to the banjo mesh.

Dandy is that the reason the designers put the banjo filter in or a shrewd deduction? Also I had not realised the filter was paper, I thought it would be a mesh of some sort.

And an old filter when it starts breaking up..

Erm..........shrewd deduction Ron - there's got to be something hanging around a new filter - or as teen says, when an old filter cries enough

I can imagine, if the filter breaks up and you dont have the strainer fitted you will be CRYING.

I'm sure your right about fibres in poor quality filters and failed filters with the banjo filter providing a final trap that due to its size would quickly block and shut down the engine as a failsafe.
Logic says that the banjo filter can't be finer than the main filter and doesn't need to be.
Cleaning mine 3 times after problems and not finding any particulates I decided to leave it out. I assumed that the problem was something producing a gum when hitting the hot IP or congealing when cooling over a period of time. Possibly due to the addition of bio to regular diesel although I hadn't had a main filter problem.
Ok mine has only been out for about 10000 miles, no time at all in the terms of pump life, also very little diesel is used as I run 100% virgin veg oil except for starting up first thing and then shutting down.
