Interesting test on post 2 micron fuel fiters

[BigRAWesty]

Just seen this on FB.
A pretty fool proof test which settles a lot of thoughts against post fuel filtering to 2 microns...

I think my mind is made up..

He does lol..

Its not really conclusive....

It needs gauges (pressure and flow) post filter. They are only looking at pump suction. This will remain the same regardless of a restriction beyond it.

The pump will also compensate for the extra load hence return fuel stays the same. More load is being applied to the pump.

to me, regaurdless pump compensating for load to make up fuel flow, the vacume pre pump after the filters is what I was looking at..
If there was lots of restrictions in the filters the pump would be suckling like a whore to try and get the flow needed..

I guess that's why you pay for a quality filter..

Yes but you cant just look at pressure. Flow rates should considered first.

if you are useing bio i would use one if your useing quality fuel not needed really

Totally agree...

Yea for sure.. and around town not hard to get..
When your remote it's very unknown..

When I had the Stanadyne Fuel Manager with 5 Micron filter on my CRD it really degraded performance. I am not sure if it was the 5 micron filter or the 2+ meters of extra fuel hose to where it was installed (behind second battery). The engine really struggled with fuel starvation. Not much power. Hard to rev it quickly.

These guys are using a 2 micron Stanadyne filter. I do know they have a mounting bracket that places the filter just behind the OEM filter and only adds a few centimeters of extra fuel hose so maybe that would make it work. Otherwise, my experience was not positive with using a pre-filter on the CRD. I felt the extra resistance would kill the fuel pump early rather than protect it.
