add 2 micron cat filter

I took some pics, can you tell me which line is the pressure line to the engine?
And how do you attach to the aluminum tubing.

And what is this unused bracket with 2 ear holes for?

I was thinking of using this filter head which has a steel thread insert.

Fleetguard Head Fuel Filter Part No: 142784S
Says it has this, is it ORB boss?
Quote:
Fuel inlet and outlet ports are 7/8-14 UNF-2B
I would prefer a non ORB, cause a 7/8 ORB fitting is $10 each.
Anyone have a better idea for filter heads?

I think the top bigger line is the supply line?
And is it metric or is it 3/8" size?
I called the hydraulic store, it is a 5/8 ORB, a -10 fitting. $3.72 each to go to 1/2" female NPT. (2216-8-10s)
Then you can get a compression fitting, a '68x6x8' for 3/8 tubing, and 1/2" npt male pipe for $3.50

So you could simply use all metal connections. I dont know what is usually done.

I can't tell you off hand which is which, but a simple trace of the line up to your stock fuel filter will tell which is supply. There should be one line to the filter, then one line coming off the rail I believe and that should be return. There are some better options location wise out there for adding a 2 micron filter into the system. Adding it after the stock fuel filter is best IMHO, plus you wouldn't have to cut into a perfectly good steel line.

I checked the line with a magnet, does not stick. so either its aluminum or a real good grade of SS (doubt it)
Someone is selling a kit. But I can do it a lot cheaper. They tied into the 3/8 line and the 5/16 is the drain to tank.

And the pf7977 filter is absolute 5 microns which fit in the stock housing, better than stock which is 7 micron and also filters the water out.

I have changed my initial idea. I am going to use a 21 micron 33118 Wix for a detroit diesel 60 series as primary, then put the 2 micron Cat next inline. I have head the DD filter head salvaged from an old Chesapeake deadrise workboat a long time and makes sense to use it now. Primary and secondary makes sense and wont cost me much more. Having just the 2 micron might make it clog up faster. How do you know when these filters clog?

I may need to relocate the plastic tube holder bracket on the frame. Likely going to use the A1 marine nylon lined rubber fuel line in front of and after just for making it more flexible. Plan to use compression fittings on the fuel tubing, 3/8" OD x 3/8" Fips and then put a 3/8 hose barb on that for the hose.

OR, I do have a 90 degree 3/8 compression by 3/8 npt I could use on the inlet to the primary, which would save me a little money. Not having a rubber hose though makes it tougher to line up right. The inlet in the photo is the 90 degree street elbow.

It would be easier to add the cat filter between the fuel filter that is already on the truck and the CP3 pump. Just a suggestion.

Here's what I did. A couple of Baldwin bases, $21 from Amazon. Hose and fittings from Summit racing. After this Michigan winter though, I'm going to add a 100W heating wrap to the water sep. and fashion a couple of koozies for the filters.

The bigger line is the correct one and it's stainless. Nice clean filter set up Mbuechle.

Interesting, looks like you simply cut the metal fuel line and shoved the rubber hose on it?
I may try to bubble flare the cut ends. Rent the tool at Autozone.
I actually don't have too much issue with no flare as the pressure is low enough, but if I did that, I would double up the clamps. My cost though is 2 compression fittings, I already have 3/8 hose barbs. I even thought about using 3/8" 1/4 turn handle toilet ball valves from H Depot. Meaning you could turn the valve off and on. Would that be useful when changing filters?

I could see how the frame bracket (first pic) could be used as you did with it supported on the one end then the support struts.

I was thinking for the Detroit 60 series filter head of drilling the frame rail and tapping in two 3/8 bolts, then the other is so far held on by the 3/8 pipe but I may be able to fashion an angle bracket. So mine would be inline along the frame rail side.

As far as mounting these filters in the engine bay, there just is no easy room or way to do it and it clutters up the space.

That ^^
Filter smaller down the line, otherwise you will be using 2mic filters very quickly where maybe a 14 and a WS would work. You have 5 in the stock can (and yes, it is known around here that the Baldwin pf7977 is the wise choise), the 2-3 goes after. I'm running a Donaldson 551313 there.

There's a gigantic thread around here that has ridiculous amts of info.... here it is: https://www.cumminsforum.com/forum/3...water-sep.html

OP, per the Cat fuel filter install kit instructions, the upper line is the supply. FYI: the Cat kit uses compression couplings attached to fuel hoses. This allows a little flexibility if the installer doesn't quite cut the OE line in the right spots. And it makes for an easier line install.

Learning about these filters, there are so many to choose from.
The 1-12 Detroit Diesel filter head has many filters available, also some are water seperators, and I like the steel insert center threads on the head, so no galling of threads possible. It is also zinc diecast, its heavy, so not aluminum head.

Apparently that Cat 1R0750 is aluminum and the 1-14 filter head I bought is aluminum which is sort of a bad idea, but I found a P553203 WS or Wix 33005 WS 3 micron made of steel which sounds better to me. So that Cat 1R0750 may be the last one I buy. I could have WS filters on both primary and secondary with decent micron ratings. I suppose some grease on the threads and do not tighten tight.
WS stands for water seperator, at least they have a drain.
Some I have found of interest are for a 1-12 head, for my reference so I dont lose the numbers.
Baldwin BF5800 25 micron
Baldwin BF5813 WS

Luber Finer LF P815FN
Luber Finer LF8010 WS

Donaldson P558010 20 micron
Donaldson P553203 WS

Fleetguard FS19513 WS
Detroit Diesel 23530706
Detroit Diesel 23512317 WS
Detroit Diesel 25010793

wix WF10045 WS
wix 33123 12 micron
wix 33118 21 micron
wix 33418 WS 12 micron
wix 33646 WS 20 micron
wix 33764 WS ? metal screen filter
wix WF10014 WS 4 micron
