nwtdiesel Posted June 13, 2013 Share Posted June 13, 2013 (edited) We just got another batch in of our 01-2010 Duramax CAT filter adapters. We sell these all over the country to other diesel shops and customers. We designed this about 2 years ago and what it is is a adapter that screws on to your stock Duramax filter housing and allows for a 2 micron CAT filter to be screwed on to the adapter. This gives you better filtration for longer injector life and the filter is also a fraction of what the OEM filter costs. We run these on fleet trucks, stock duramax trucks, hi performance trucks and trucks with and with out lift pumps. The reason i designed this was because of all the issues the duramax owners were having with short injector life due to crappy fuel. People love them! We have heard reports of small mileage gains, longer filter intervals, smoother idle and of course huge savings not only with a cheaper priced filter but the injectors are lasting much longer. We have around 100 in stock at the moment but they will sell out in a few weeks. If you want one installed we do it for $125 out the door. If you want just the adapter they are $59 and the filters are $20. For you Cummins and Ford guys we do sell and install the Airdogs and FASS fuel systems which also filters your fuel better then OEM. Dont forget to come to us for all your fluids and service needs! We carry Amsoil, Schaeffers, Rotella, Delo, Wix products. Thanks! 702-737-7333 www.undergrounddiesels.com Edited June 13, 2013 by nwtdiesel Quote Link to comment Share on other sites More sharing options...
ynot Posted June 13, 2013 Share Posted June 13, 2013 What's your price for a LOF and change over of the fuel filter for a 2003 F250 6.0? Quote Link to comment Share on other sites More sharing options...
nwtdiesel Posted June 15, 2013 Author Share Posted June 15, 2013 What kind of oil do you use? We use Wix filters. Quote Link to comment Share on other sites More sharing options...
andydew Posted June 15, 2013 Share Posted June 15, 2013 ? We use the cat 0749 on all of our big cats; any chance those would spin on your adapter, or is the 0750 filter threaded differently. I'm thinking this would be a smart move for me, especially if I could only have to stock 1 filter size on my shelves. Quote Link to comment Share on other sites More sharing options...
bp-guy Posted June 15, 2013 Share Posted June 15, 2013 How does the adaptor secure to the motor? Or does it all come off when changing the filter. What would shipping be to San Diego? 91977 zip code Quote Link to comment Share on other sites More sharing options...
sanddunesaddict Posted June 15, 2013 Share Posted June 15, 2013 it just screws on before the new filter Tim. I have one on mine. I even noticed a difference at the top end of rpm band. It doesn't seem to layover as it did with a stock filter. The Cat flows more and filters better. 1 Quote Link to comment Share on other sites More sharing options...

nwtdiesel Posted June 17, 2013 Author Share Posted June 17, 2013 (edited) The 0749 is the same thread as the 0750 and yes the 0749 will fit. Its just a longer filter. I have customers who run them. Shipping is $59 to the lower 48 for the adapter. Edited June 17, 2013 by nwtdiesel Quote Link to comment Share on other sites More sharing options...

sanddunesaddict Posted June 18, 2013 Share Posted June 18, 2013 its deleted. If your worried about it you can buy a filter that will work with a separator. If you get your diesel at good places with lots of volume you don't need to worry. 1 Quote Link to comment Share on other sites More sharing options...
bp-guy Posted June 18, 2013 Share Posted June 18, 2013 I wasn't worried, Just wondered what to do with it. Tape it up out of the way? Or is there a connection I can unplug it somewhere? Quote Link to comment Share on other sites More sharing options...
sanddunesaddict Posted June 19, 2013 Share Posted June 19, 2013 yeah you unplug it right at the filter and it will just sit there in the harness Quote Link to comment Share on other sites More sharing options...
nwtdiesel Posted June 19, 2013 Author Share Posted June 19, 2013 Yes just tape it up or zip tie it out of the way. It wont throw a light or anything being unplugged. Quote Link to comment Share on other sites More sharing options...

bp-guy Posted July 23, 2013 Share Posted July 23, 2013 (edited) Thanks, I put it in yesterday. Real easy install. I noticed the idle fluctuated after the change over. Drove it to work today and it went away. I will post more in a day or two on how it goes. One thing I noticed but it didn't effect anything- When installing the new fuel filter it was hitting the side of the motor just a bit. It didn't hinder anything but the filter didn't just screw on easily, I had to help it out. Other than that I was happy with the whole thing. Too pretty of a piece to hide on the side of the block like that. Edited July 23, 2013 by bp-guy 1 Quote Link to comment Share on other sites More sharing options...

Too pretty of a piece to hide on the side of the block like that. The fluctuation you felt is from the air in the system after a fuel filter change, that will happen with any fuel filter. Will happen usually on first or second start up if you dont let it idle for long. If you had a issue i apologize but from all the filters we test daily and install, we have never had/heard of a CAT filter touching the side of the motor, we have sold thousands all over the country and this is the first i have heard of this, we test fit each one before they leave UDP. Tons of hours of R&D went into the adapter and i made sure there would not be a fitment issue. The filters do screw on easily so not sure why you had a issue, we also screw the CAT filter on the adapter before we ship them. I assemble each insert by hand, inspect the threads, screw the filters on and screw the adapters on a test filter head. Everyone installs them different, some guys like to screw the filter on before the adapter goes on but once the adapter is on it shouldnt ever come back off just take the filter off. Its easiest to take the extra time to take the plastic wheel liner out when installing te filter. Thanks for purchasing and your injectors will be happy. Let me know if you need anything. just got back from a duramax spa trip to underground diesel . oil change, fuel filter cat adapter, and flash tune for towing and milage.. i also just put new bilstien shocks all around. truck seems very happy ! thanks for getting my in before i leave on a road trip mike Thanks for coming in and hope your happy!

nwtdiesel Posted July 25, 2013 Author Share Posted July 25, 2013 These must be getting popular around town, Cashman CAT called today and asked we bring in some cards, they said they are getting asked atleast once a week about these adapters and they are sending people our way. AWESOME! 2 Quote Link to comment Share on other sites More sharing options...
bp-guy Posted July 25, 2013 Share Posted July 25, 2013 No big deal on the filter issue. It went on and works like you said. I don't know if it is just me but the motor seems to run smoother on the freeway. Quote Link to comment Share on other sites More sharing options...

I don't know if it is just me but the motor seems to run smoother on the freeway. Im glad your happy! I want to make sure there are zero issues is all, thats why we test them all here before they go. We have had reports of smoother engines and mileage gains too. Keep a spare filter with you at all times, these filters catch all the debris and if you get a bad batch of fuel somewhere it will clog it up but you will still be able to limp it home or to a autozone. It happened to me once when i filled up with crappy fuel. Quote Link to comment Share on other sites More sharing options...
andydew Posted July 25, 2013 Share Posted July 25, 2013 ^10-4 on that. These cat filters are the best; but because they filter down to 1 or 2 microns, they can plug, but that's a good thing...don't want sludge going any further than the filter. I always carry extras, and a filter wrench. I've used them too! Quote Link to comment Share on other sites More sharing options...
