Re: Diesel Filler neck and cap for auxillary tank
Its going between the transfer case and main tank. My truck is a CC short bed 4x4. If it was not for the 4wd I could run a much larger tank. This tank will be about 18gal, it will hang about 1" lower than the stock tank, but still higher than the cat.
I figured 18 gal would give me plenty of extra range, but after towing my dyno trailer with a car on it I was getting 10.5-10.9mpg (about 11,500 lbs for dyno trailer with car). With just the dyno trailer (8,000lbs) I get around 13mpg.
