Let's face it, any gas tank can be ruptured in an accident. I do not like the outside-the-frame mount, the in-cab mount nor the rear mount. Again, JMHO.
Any tank underneath a vehicle is subject to debris damage, also. Oh well, thanks for y'all's input-I will give a report on my final answer!

 

Has any one looked into fuel cells? My son runs one in his rock crawler. He rolls it over and it never leaks. Probably not cheap.

 

Jim,

I have looked at fuel cells and I am leaning that way.

Link to a 19 gallon fuel cell with 90 ohm fuel sender installed. Dimensions are 30L x 12W x 12D .Add a rollover vent valve, a 45 degree filler neck and route the filler to the side of the bed.

If this one is too wide for your comfort, there is a 15 gallon version that is 30L x 9W x 12D that will give you more clearance for the drive shaft.

JJ,

Does a fuel cell require a special fuel pump?

 

is this the truck that was on Craigslist in Mt. Aimy?

 

No, it is not.

 

No, it does not. A fuel cell is nothing but a gas tank. These happen to be made from aluminum, have two 1/2" fittings for fuel line and return line and a vent port. You can use a regular engine mounted fuel pump if you are running a carb or you can use any of dozens of different types of electric fuel pumps for either carb or fuel injection setups. You will need to use a reducer to change from the -8 AN fittings on the tank to your existing fuel line. -8 lines are way more than are needed for a street driven truck.

 

here's a pic of my "slick" it had a 60 gallon fuel cell/tank under the tool box. The one issue I had was trying to fill the sucker! I had to keep about 20 gallons in it all the time so it wouldn't run out of gas. I'd have one again in a heartbeat. The inlet was in the tool box on both sides.
