Fuel pressure

[a5150nut]

Sorry it's going to take me a bit to remember this forum is here.

I don't actively monitor fuel system restriction/pressure. Instead I have a gauge that I use as a tool to check periodically.



I won't get caught up in all the 2 micron over rating BS, but I will say that I do not care to have the best filter first in line and also don't care to have to do a quick filter change on the road as it means wearing diesel.

That's alright John, change takes time.

And I agree primary should be a rock filter, secondary a little finer. But that is the way the truck came. I am considering one of your pumps between the tank and primary filter. 1/2 in line is already there just need the pump and two fittings and drill the bracket to mount the pump to it. I already have a Donaldson 4 mic to replace the stock filter.

I was just trying to find some sort of fuel pressure guage to monitor filter life. If nothing else a <1lb murphy switch and an idiot lite.

I prefer to shut the pump(s) down and go by restriction as it's more precise. Otherwise any gauge any place just keep the scale small.

The OE filter is 4 micron these days. Not sure about the WIX plastic garbage, but a true OE spec multi layer element would be.
