We had a gent have his Duramax towed in to the shop after filling it with gasoline. Yea he filled to full with gasoline in a diesel truck. Managed to drive just about half way home and it died. So went through the process of draining the fuel tank, disposing of the mixed fuel, and putting 10 gallons of fuel back in. Now Lindy ask me to change the filter. OMG! I'm looking at this going it going to be fun. Drain the filter and spun it off. Now how in the heck do you get it out. I finally figured if you drop it into the A arm on the passenger side then you can lay on the floor and lift it up and squeeze it back through the fender skirt. So now reverse process of installing. No fun at all. Then hearing about the price of a Duramax filter I about choked.

it's sad how the "engineers" that design the vehicle never have to work on them.  my friend here in Flag just replaced his CP3. had to take entire front of engine apart for the most part. he was not happy about where they put it.

new one ready to go in.

 

sure glad it wasn't my truck.

We always cut the inner wheel well on the d-maxes

Water pumps on a d-max are just as bad, major project to swap.
