I will be adding a racor diesel fuel water/separator and I was wondering if a 2 micron is too restrictive or if I should go 10 or 30 microns?

This would be the one RACOR Spin-On Series Diesel Fuel Filters/Water Separators | West Marine

Specs
Racor's Aquabloc filter media removes virtually 100% of water and solid contaminants. Filters have die-cast aluminum heads and come in different sizes for diesel engines and any rate of fuel flow. To be used on the suction side of the pump.

See-thru bowls allow visual inspection for water; metal bowls are recommended for use in areas of high heat and are required by the US Coast Guard on inboard engines and gensets.

Fuel Type: Gasoline or Diesel
Mounting Style: Bulkhead mount, spin-on element
Flow Rate: 15 gph
Mounting Head: Die-cast aluminum
Inlets/Outlets: 1/4" NPT female
Bowl Material: See-thru polymer
Drain Fitting: Stainless-steel plug 1/8" NPTF
Overall Size: 6.5"H x 3.2"W x 3.2"D

I have noticed most of you guys are using the gas version but I would be going with the diesel version as thats what we use on our boats.

Thanks in advance.

I read that somewhere but I just want to add one for piece of mind. Just adding also a coolant filter and an additional oil filtration system.

This would be a tow 5th wheel truck for long distances and want to make sure my engine has an extra protection/filtration. Thankfully no water issues.

What size should be inlet/outlet?

You would go larger on the inlet/outlet or the filter it self?

i don't know what size inlet /outlet for the 6.0
but my motorcycle and lawnmower use 1/4 in and out

I would atleast think 1/2 and you theis a return style system so i would want to know the exact GPH required at a minimum

if your not monitoring fuel PSI don't ad any restrictions IMO

Slight derail here, but it applies to this subject. I was talking about this kind of setup with my uncle the other day. He has a 6.7 that he bought about 2 years ago or so. Anyway, he expressed concern for the kind of fuel hoses available on the market and whether or not they can hold up to Bio-Diesel long term or not. He did a ton of research and found a manufacturer that makes it. Then he got busy with other projects last year and lost all his info on it. But that's the last piece of the puzzle that's keeping him from installing his Racor water separator system. Does anyone know anything about how normal fuel hoses fair long term against Bio-Diesel? He lives in Minnesota where State law mandates that all Diesel fuel sold for on road vehicles must be Bio Diesel so between State Law and the extremely cold winters, it's a very real concern for him. Are we nuts?

He can't get it in Minnesota. They sell what they call "Off-Road" Diesel up there which would be no bio straight #1 or straight #2 or blended depending on how stinking cold it is BUT it's dyed red and if you're caught driving with it on a state road or highway, you're fined heavily and that dye doesn't go away for a really long time I guess. Sucks. I only know of 2 gas stations in my area here in Central Illinois that sell straight #2 no bio and I fill my truck up there religiously but if I travel anywhere, I have to fill up with Bio. My truck HATES bio. Anyway, Bio is everywhere and Uncle Bob doesn't want to run some crappy fuel lines off his fuel pump to and from his Racor setup that will deteriorate over time because of the Bio fuel he's forced to buy. He's a pretty smart dude. On a good note, his 6.7 seems to not hate Bio like my 6.0 does. He probably doesn't even really need the Racor. But piece of mind is priceless when it comes to a $40+ Thousand dollar pickup truck when you're retired and pulling a toy hauler all over the U.S., Canada, Alaska, etc...

I see no reason to add another filter.
