Fuel Filters-Microns????

[89GQ]

Hey all, Whats the story with microns in the filters? Is it the more microns better filtration, Is 5 better than 10 microns etc. Cheers

The more microns the finer the filtration........... & thats the story...................lolol

You sure Paul?

I thought the less microns the better the filtration.
ex. 5micron filter will filter particles 5micron small where the 10 micron will only filter particles down to 10 micron and let anything smaller through....if that makes sense

Cheers lads, Just trying to work it out, Went past a injector/diesel shop today and the guy said ille be getting restricted delivery of fuel due to my cav filter after the original one????Cant see it myself! Iv'e run it since new! I know the cav is 5 microns (i been told) dont know what the original is rated at.

Going to try a photo I thought it was low preasure before the Injector pump and high after it. Confused,but its allways ran well.

Was my photo too big????????

I think what his concern is , is that more filtering slows fuel flow. Diesel is slighty thick and hence takes longer to strain through finer filter. Yes low pressure before pump and higher on output is right. Maybe run a ten micron next time and see if you notice a difference. It may be only noticable on your idle.

Will find out if the cav can be a 10, Anyhow next job is injectors and pump, Thats why i went past diesel place,Was weird he said all the reduced flow etc. etc. but when he started it he asked why do you want to renew any of it, It starts as good as new , have you done youre IP and injectors,I said thats why ime here its on 300 thousand and never been touched! so he went quiet and said 2-3 thousand new injectors and reco pump and G-plugs. What to do leave it??I think i will do it! Maybe not their though.
