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!

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, 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.

I got this setup. Going to install it in the next day or so.

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.

what's wrong Jim cat got your tongue??!!!

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.
