Anyone done a duramax conversion

I think they are 1/2 supply & 3/8" return.

You will have to do some work to make the dual tanks functional. Check out the fuel tank switches used in marine applications. They are made for high flow & also switch the return line as well.

IMCO Marine makes a heavy duty, Coast Guard approved (i.e. safe), 1/2" in/out, 6-port fuel switch. I've had one on my truck for well over a year and it works great. I run a toolbox.tank combo as well as my factory tank.

I still have to find a ford dana 60.

Where are you located? I know where there is one.

if the truck is just going to be run as a puller is there really a need to keep the stock tanks i would just use a fuel cell in the bed it would be a big savings in weight and a heck of alot easer to make work just food for thought

thanks that is true. i cant belive i didn't think of that lol. but i still want to drive it in the summer alot so i might just spend the money and keep the headache with trying to do the dual tanks. i would hate to speed 10 grand on paint and body work just to have empty fuel doors, becuase i would have shaved them.
