Dual Fuel Tanks
I checked my owner's manual about the dual fuel tank operation and all it basically said was to make sure one tank does not go completely dry before switching. Does that mean I can switch fuel tanks on the fly? I didn't want to try it until I got some other folks' opinions.
Thanks.
Thanks.

You can switch any time you want.I just let off gas for a second.
Did you find stacks yet . Check with any truck repair they would know of a place or a truck sitting to get them off of. Good luck

I used to run my tanks dry before switching all the time with my gas truck. Never had a problem.
Have run the diecel dry on each tank just to see what happens & how much fuel they hold.
Haven't hurt anything yet. Switching on the fly is absolutely ok.

The rear tank on my '89 doesn't work, but on my '85 I switch back and forth between tanks all the time.
During the winter, I use the rear tank as my "warmup tank" (warm the truck up while it's idling) and switch to the front tank for my "driving tank".

For some strange reason, my front tank reads empty all the time and no matter how full I keep the rear tank, it always reads 3/4 or less.
I just gave up and have been running off of mileage for over a year now. When I fill the tanks, I write down my odometor reading. Then I add 180 for the front tank (19 gal.) and 160 (18 gal) for the rear. I use these markers for the time to switch and I always do it while I am driving so if it quits, at least I can roll over to the side.
So far, so good.

we used to have the old chevy with the tank behind the seat i remember my grandfather tapping on it up and down to guestimate the fuel levels
looking back on this how nuts was it to have the fuel tank in the cab with the passengers, but this was also when kids ALWAYS rode in the back of the truck adn never had a helmet on the bicycle

Yup haveing it protected in the cab was a stupid idea.
