We not only did the fuel tank swap and mods on Chuck's F-250 today, we did mine, too! That's two 150-pound 46-gallon tanks, two fuel line mods, two in-tank mods, and a fuel filler neck mod for his truck (2002s don't need that one).

The good news? My truck's average mpg has increased by about 3-4 mpg.

The bad news? I can't lift my arms, my back is sore, and am I tired! But....I'm smiling! /forums/images/icons/smile.gif /forums/images/icons/smile.gif /forums/images/icons/smile.gif

Sounds like you had a productive day....Good for you. Now, go draw you a tub full of hot water, add bubble bath, and at least 1 bottle of wine to celebrate....

We already had the celebratory bottle of beer after coming back from filling up my tank. Oh boy, did it taste good!

It's not the fuel tanks, it's the modifications we did to the in-tank fuel pick-up and a pre-fuel pump modification. In the tank, the mixing bowl for the diesel fuel is deleted and the pre-pump involves removing a quick disconnect clamp and rerouting a hose. Both mods remove air from the line, which increases mpg, performance, and saves the injectors in the end. (I've been hanging out on the Diesel Forum, learning a lot about my new truck.)

O-K, you are speaking of fuel oil burners. I was hoping you were talking about gas. 3 MPG would equate to a 30% increase in my fuel consumption. I was getting excited. My P.U. is a 6!

Now why would they set it up like that in the first place? Is there any benafit to the factury set up?

That's one of the biggest questions/gripes on the Diesel Forum. Ford won't acknowledge the design problem.

At least the 100,000 mile warranty covers the engine--but not the aggravation! /forums/images/icons/smile.gif
