Make Your 1973-1987 Chevy Truck Safer by Relocating the Fuel Tank

Before they were classics, "squarebody" Chevy trucks were just workhorses. It was ok for the fuel tank to be under the cab while hauling hay bales across the farm, and a couple hundred horsepower was more than enough to get the job done. Fast forward to today and 70’s-80’s Chevy trucks are full-fledged classics that are getting the same custom treatment as early Camaros and Chevelles. These custom rebuilds often feature dramatic suspension modifications, custom interiors, and huge power from modern fuel injected engines. And they get driven, often blasting down the freeway in modern traffic with distracted late-model drivers buzzing all around. That crusty old tank under the cab floor isn’t looking so good anymore.

While previous generation C10s and even earlier model Chevy trucks featured a fuel tank in the passenger compartment behind the bench seat, the square body’s fuel tank location could certainly be seen as an improvement. However, it has been noted over the years that it’s mid-chassis placement on the outside of the driver’s side frame rail often means the factory tank can be ruptured during a traditional “T-bone” style collision. Moving the fuel tank to under the bed of the truck and behind the rear axle provides for a safer mounting location between the rear frame rails. TwoLane™ EFI Under Bed Fuel Tanks relocate the tank to a safer location and are ready for modern in-tank pumps to fuel EFI powerplants from mild to wild. 

Frame Specific Dimensions Ensures a Perfect Fit Under the Bed of Your Pickup

Moving the fuel tank to the rear of your pickup under the truck’s pickup box/bed floor provides several benefits. The most obvious of course is removing the liquid fuel storage from just under the driver’s side of the passenger compartment where a ruptured tank, separated fuel line or filler hose in an accident can quickly engulf the cab area with flames. Moving the fuel tank to the rear not only provides a higher level of safety but places a good bit of weight at the rear of the pickup, which aids in traction. On average you’re looking at roughly 100 pounds of weight with a full truck bed fuel tank. Relocating the fuel tank also provides room under the driver’s side cab area for running boards, rock sliders, custom exhaust, or to run your fuel and brake lines.

We have designed our under bed aluminum fuel tanks to mount between the frame rails for a perfect fit behind the rear axle assembly. This is not a universal fuel tank requiring modification to fit your truck. The 27-inch wide truck bed gas tank is built from .090-inch thick aluminum sheet  or 14-gauge stainless and TIG welded for a strong, assembly. An internal full height baffle reduces fuel slosh and keeps the pickup tube immersed in fuel. Mounting flanges made from 1/8-inch material on each end (for a total width of 33 inches) are configured to perfectly fit your squarebody’s frame rails. Final placement is directed via the factory rear frame rail angle and all you must do is drill your own mounting holes and bolt the tank in (hardware not supplied).

Fabricated, TIG welded aluminum looks trick, but might look out of place on some trucks. With that in mind, these tanks are also available in black powdercoat and stainless steel. The black tanks are subtle and will blend in with the other finishes under the truck, while the stainless lends a high-end touch to complement the rest of the shiny stuff throughout the truck.

Ready for Modern EFI Power

These days, lots of classic trucks need more from their fuel system than just a tank relocation. In place of those old stock small blocks and utilitarian 6-cylinders are upgraded late model engines with EFI and lots of power. Some even have power adders like turbos or superchargers and they need way more fuel than those ho-hum original engines ever did. These tanks are up to the job, set up to mount in-tank EFI pumps with the common 12-bolt, 5.375” bolt circle. There are quite a few advantages of an in-tank pump design. That’s why the OE’s have been using them for decades. Particularly critical at high power levels is the cooling effect of the fuel in the tank on the pumps. Additionally, the surrounding fuel helps isolate the sound of the pumps. Spend any time in a truck with a big external pump bolted to the frame and you’ll appreciate the relative silence of in-tank pumps. Internal pumps also serve to clean up the plumbing, minimizing fittings and potential leak sources when compared to external pumps. 

The 1-1/2-inch diameter filler neck uses standard filler neck hose and allows you to install your choice of fuel filler cap/door in the floor of your truck’s bed. 

These tanks are designed to fit common aftermarket EFI pump modules, but are also available in complete kits featuring trick TwoLane™ EFI In-Tank Fuel Pump Modules in various levels to fuel whatever is under the hood of your truck.
