Well I've read a bunch of threads about folks wanting an auxiliary gas tank in the bed of their truck. While numerous options exist for the diesel crowd, none seem to exist for the gassers. I used to have a 54 gallon tank in my diesel dually. Loved the extra range and the option of buying fuel where and when I wanted, rather than when I needed to.
So, I bought a 60 gallon RDS tank, 71212 56" Length x 13" Width x 19.25" Height Rectangular Auxiliary/Transfer Fuel Tank, from Amazon. I had it in my "Wish List" and when the price dropped $145, I pulled the trigger.
I mounted it offset to the passenger side so I would have more room for a valve and fittings.
I routed the vent hose to a tee I installed in the OEM vent line so there would be no fumes lingering around. I then welded a tube to allow the aux tank to gravity feed into the OEM tank's fill tube. I added an inline gas filter between the aux tank and the OEM fill tube.
It has been a couple weeks and only one small problem so far. Once the OEM tank is full the gravity fed gas will drain into the OEM vent line. This has caused the truck to stall 3 times. My solution for now is to only open the valve when I need the gas and shut it off once the factory tank is full. There seems to be no long-term ill effects of the excess gas draining into the vent line.
A little tube cutter took care of the vent line.
The tank is secured via the mounting tabs. The ratchet strap is just for a little extra security.
I do wish that the **** was welded at the rear of the tank to allow for easier plumbing, more room for fittings.
