Duramax CAT Fuel Filter Adapter 2001-2015 LB7/LLY/LBZ/LMM/LML (Full Install)

[@ralfie8801]

You’d never see any leaks from your filter with the engine running since it’s on the suction side of the fuel system. That’s why you have to prime the filter with that hand pump. It might suck air in and shut the engine off if there’s a leak. Also, the bleeder screw only needs to be loosened, not removed.

[@randomtask9643]

I noticed in a lot of your videos, you constantly have that passenger side front inner fender off a lot. It would be a good idea for someone to come up with an aftermarket one that allows access doors/panels so you didn't have to constantly remove it. I know some heavy equipment (Cat haul trucks) have that option specifically for that reason so the mechanics don't have to mess with it during PM's

[@iLLeag7e]

I think there is a huge untapped market for custom panels just like what you described. The thing is, simplicity is life's greatest luxury. Anything that pushes you towards that end would probably sell. I have insane sciatica so "simple" ways to do repetitive things would be so much better for me than fancy shit. I'd be one of those lame billionaires who is stupid happy with a bunch of stuff only I think is cool. That's not true, everybody loves hookers! jk don't love those thos

[@arfifteenguy]

I did this about 3 weeks ago and love it have to protect those injectors. Your decals look amazing

[@donhagell]

Installed this on my 2016 Duramax. Pretty easy to install after watching video. (newbie started doing own work after warranty expired)

[@pigslayer106]

my LBZ has the cat filter adapter with no aftermarket expensive lift pump and has over 300,000 miles with zero issues

[@danbrooks9986]

Did you have to talk the ball and spring out of the primer ?

[@enriquepalomino8636]

I had put the 1r-0749, huge filter it looked wicked. I removed it a week later when I realized it did not have a water separator. Since I don't have a lift pump yet I put the stock filter back on. When I get the lift pump I'm gonna run 1r-0749 on lift pump with a cat fuel water separator and another 1r-0749 at the front where stock filter is at. Better filtration, healthy injectors.

[@thomasvizcainco5658]

I did this and ended taking it off, the stock filter is actually better. However it does not make any lights go on .

[@jejc1001]

Also have water sensor and a petcock to drain water..I drain mine every 3-4 fill ups. Water in fuel warning hasn't came up on my dash in years. I have an 05 lly

[@hugoromero8377]

Hey man I just wanna reach out and say thanks for all the hardwork! I got an '02 LB7 and I always come to you when needing info.Thanks for the videos brotha! Greetings from good ol San Antonio,Tx🤙🏼

[@TruckMaster]

Thanks brother

[@bernardshelton7349]

I put this same filter on my 04 Duramax Lb7 I really like it. I bought a extra filter for my emergency filter if needed before the change is due.

[@robertg086]

Put a cat adapter in my LB7 when I did injectors from Duramax store. get the BOSCH ones!!! I also did a dual lift pump from Kennedy diesel and a baldwin fuel water separator just after the lift pump. Checked for water after 5k miles... Maybe a drop of water came out. Happy with the setup! CAT fuel filter is a huge upgrade for these injectors!!!!!!

[@robertg086]

Get the billet aluminum bleeder screw too... If you suck air in here you will mess your injectors up. A good o ring will last a long time... Factory plastic plug is known to crack and let air in....

[@Todd1975W]

I will have to say very fast shipping wow, I got mine today and 25 minutes later installed. (20) minutes for the work and (5) minutes just to find my wrenches LOL. I would recommend everyone to get one of these for the cost vs. repairs seems like a no brainer to me so thanks again for sharing.

[@TruckMaster]

+Todd no problem glad it worked out!

[@Todd1975W]

I guess I will have to call Sinister the kit is leaking air after about 150 miles the truck wouldn't start with out priming it up. Just wondering if you had any issues with yours maybe its just a bad O ring on the adapter. When I pulled it off to check it I didn't find any tears or nicks so I put the stock filter back on and no problems after that. I still want to run the CAT filter so far I can find no visible problems with the filter or O rings.

[@Todd1975W]

I finally got time to post my Duramax video been working all the time. here is the link check it out.... kzbin.info/www/bejne/iGjce397qsxjfrM

[@johncasor9698]

i was a fleet diesel Mechanic for 23 years... and i always filled the fuel filters up before installing them something you should know... and same with the oil filter fill them up first...

[@andrewguillaume1836]

You wasted your time for 23 years then

[@paulc4414]

Nice how-to as always. If you have a lift pump, you can use that to prime the system after a filter change.

[@TruckMaster]

+Paul C thanks

[@2015CTD]

Don't forget to remind folks that if they do do this install they will lose there water separation if they don't have a fass/airdog great video though and awesome decal badass

[@DaJokrz]

063rdgen 2500CTD good point. This filter should only be used with a lift pump using a water filter. For those who don’t have a lift pump but decided to run a different filter, the Donaldson P553203 is a good filter that will seperate water from the fuel and has a drain in it.

[@chrisao1987]

Cat makes one with a water separation built it that will work.

[@jakek7112]

What does that mean? Is there a critical extra step after this install?

[@masaallen1009]

The Traveler cat doesn't make shit. Baldwin makes the filters and paints them per order.

[@JohnSmith-qc1pb]

Does the donaldson filter fit on the stock holder or does it need a adapter?

[@juanrazo6846]

I've done that and taken it off .you have to use the filter that it came with. i bought a case of equivalent filters and kept getting air .my loss .there is a flaw on the desight that dont allow enough tolerance to accept any other filters so if you install it always keep an extra. Just in case its not a regular stock item

[@davidjackson9785]

You don't need that filter, or any filter in the factory location if you already have an aftermarket lift pump like an Air dog or FASS.

[@rodleypumpkins4174]

David Jackson totally agree. I can’t stand when guys do that mod specially if they don’t have a lift pump and if they do have one what’s the reasoning when you have a low micron filter with the lift pump.

[@EC-um2kh]

what are you thoughts that these cat filter may be to restrictive for use with a stock fuel pump?

[@yangp2k]

Saw your video recently and one adaptor I was looking at required you to take apart the fuel filter head and remove a restriction ball. Saw you didn't do that with yours. Any difference?

[@Cumminsmcgee]

Does it make your check engine light came on

[@ellishaveman4207]

took cat setup because you forgot to mention that you have to have a fuel up pump to handle the water seperation, which I don't have!, thanks for lots of info!

[@TruckMaster]

Thanks

[@royalcpnut]

I use this without a fuel pump is that a bad thing? Or is it still fine to run this fuel filter without a fuel pump on my LLY duramax

[@RBoysMedia]

Had to play with mine… after I finally got it started I found my fuel filter housing had a leak. Air was getting in preventing from starting. Started looking for a new o ring because it was leaking between the housing and the cat adapter. Ended up being the filter just wasn’t on right enough lol

[@willwilson5907]

Love everything about the video, but even though you’re getting greater filtering ability, you lose the water separator, which is important?

[@TruckMaster]

Your right after I thought about it later I changed this out to a filter housing cap

[@duramaxdave4602]

U mean u took the cat adapter and filter u had just installed off and went back to stock?

[@chrisao1987]

If you have a lift pump then you have your water separator. This is nothing more then a 2 micron secondary filter. Bosch actually recommends a 2 micron fuel filter with their injectors. However having 2 water separators isnt a bad thing if you want to keep the stock filter with the lift pump. If you do not have a lift pump do not add one of these filters till you do.

[@bjgibson32]

@@chrisao1987 thanks for this knowledge because I was looking at the cat filter and after this I definitely think I wanna keep my water separator filter for sure. Thanx 4 the heads up

Do you have one? I'm looking at getting one I wonder how they hold up

[@ghostwriter6699]

Literally took me less than 15 minutes from start to finish ... just reminder that the bolts on a 2008 are a 12 and the replacement are a 13mm ... also i found that if you undo one bold and start the new one .. and then undue the second one -- you don't have to drop the fuel housing at all .... I replaced my two FASS filters with CAT and the front Hood one and I swear I have allot more get up and go ...

[@jeffterry2250]

How often should the CAT filter be changed?

[@Palantir_Daily]

I change mine every two oil changes. I believe that is EXTREMELY conservative. It could go much longer.

[@shaunhuckabee5904]

I know this is an older vid but I installed this on my LML. I put it on hand right and it has loosened up on me twice since the install. Think I’m just gonna go back to stock until I get my FASS lift pump and delete the factory fuel filter.

[@JWMontoya]

That’s perfect! I was looking into doing that!

[@nathanielwojciuk5735]

Why didn't you remove the float valve? The directions on mine say that you need to remove the guys and take out the spring and ball in order for the filter to work otherwise it won't and motor won't get fuel. And I've read reviews that say the same thing

[@NaztyNate]

bad ass upgrade. have a similar kit and love it! so cheap for new filters lol

[@lewisbrashear8121]

I’m confused because you took the water separator offline. How are you supposed to separate the water from the fuel now?

[@mooserollingentry3916]

Yo how do I drain the water ? Do you still need to ? Or does the cat store water ?

[@freddieburchfield751]

I installed a Holley 14psi 140 gph fuel (boost pump) and a Balwin filter with a water drain between the tank and the stock filter location.

Do you normally run the inner fender liner? Or did you just remove it ? And also does this throw any codes, I.E a “service water in fuel sensor” ?

[@mikef6706]

I thought about this mod until I read you should have a lift pump. My 07 Classis I could change filter w/o removing fender liner. But my 07.5 New Body style I just can not do it w/o removing liner. Do they have replacement o-rings and does the adapter back-off when changing the filters? I did not see a locking stud.

[@ghen1913]

Great vid on the install, but I would have to agree with some of your other subscribers, you already have filters on the lift pump, I installed FASS filter delete on my lly....

[@thebirdmanis]

No need for 2 filters if you do a fass delete. I removed my CAT Nicktane after installing the FASS. No more diking around with a stock filter👍👍saving a couple bucks too.

[@buncherkev2794]

One day when your fass quits and you have a fuel problem your going to wish you had the primer. Ask me how I know!

Buncher Kev I still have the primer, it just deletes the filter itself, a filter can easily be reinstalled.

[@buncherkev2794]

Same here - the FASS delete kit simply replaces the factory filter with a bowl that can be removed if you want to spin another filter on.

Coming along nicely. 👌 I tried installing one with the adapter on my Lb7 and I couldn’t get it to work. Can’t you also remove the spring from inside the of the fuel filter and pull that white plastic ball out?

[@sav300]

RC LB796 I did that on my LB7 when I installed my adapter. It's a check valve from the tank so you don't have fuel returning on the suction line I believe. Not 100% on that. No issues after 80k miles.
