Make Your 1963-1972 Chevy Truck Safer by Relocating the Fuel Tank

Before they were classics, old Chevy trucks were just workhorses. It was ok for the fuel tank to be behind the seat 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 60’s-70’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 behind the seat full of sloshing fuel isn’t looking so good anymore. TwoLane™ EFI Under Bed Fuel Tanks relocate the tank to a safer location and include TwoLane™ EFI In-Tank Fuel Pump Modules 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 inside the passenger compartment where a ruptured tank, separated fuel line or filler hose in an accident can cover the occupants with gasoline. 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 a bit more cabin storage room, or space for audio gear, road trip tools, and so forth. For 67-72 truck owners we even offer a fuel filler delete panel to cover your factory filler hole in your truck’s cab.

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 fully TIG welded for a strong assembly. An internal full height baffle reduces fuel slosh and keeps the pickup tube immersed in fuel. Generous 2-inch wide and 8-inch long mounting flanges on each end (for a total width of 31 inches) fit within your truck’s frame rails. Final placement is directed via the factory rear crossmember 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 anodized 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 kits feature the trick TwoLane™ EFI In-Tank Fuel Pump Modules in various levels to fuel whatever it under the hood of your truck. 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. 

In addition to the tank and pumps themselves, these kits include a billet 12-bolt top plate with an AN-10 fitting on the feed and AN-8 fittings for the return and vent, submersible EFI-rated hose and clamps, fuel pump pre-filter sock, wiring pigtail with weatherproof connector, and the pump mounting bracket and hardware. Everything you need to power up your EFI swapped C10. 

255S – This kit provides not only a bolt-in tank custom tailored to your truck, but also a trick in-tank pump module featuring a CNC-machined billet lid and a tried-and-true Walbro GSS340 pump that flows 255 LPH. These pumps will support up to 500 horsepower on gasoline and are perfect for stock or cam-swapped late-model engines. We’ve logged thousands of trouble-free miles on our own trucks with this pump feeding a variety of late model EFI V8 engines. 

255D - A single pump is great for stock and cam-swapped NA engines, but if you’ve added forced induction or nitrous to your truck, adding a second pump not only provides more fuel, it also provides another way to help you dial in the power. These in-tank EFI modules feature two proven Walbro GSS340 pumps and will support up to 1200 horsepower on gas. This dual pump setup is ideal for turbocharged or nitrous setups where staged fuel delivery is key. Individual pump wiring leads allow each pump to be controlled separately, reducing heat and fuel cycling when full flow isn't needed and allowing you to signal the second pump when additional fuel is needed under load or boost.

E85S - This kit allows you to cash in on the affordable octane in E85. It takes a dedicated fuel system to handle ethanol. Not only is E85 corrosive to components that aren’t designed for it, it also takes more of it to keep AFR’s happy when compared to gasoline. This tank kit includes a module equipped with a single Walbro F90000267 pump that flows 450 LPH and supports up to 750 horsepower and is designed to meet the needs of an E85 system.

E85D - Equipped with dual Walbro F90000267 pumps, this tank kits supports up to 1,200 horsepower on E85. This dual pump setup is ideal for turbocharged or nitrous setups running E85 and can be staged to signal the second pump when additional fuel is needed under load or boost. 

450S - This tank kit uses a big Walbro F90000274 pump that flows 450 LPH. That’s enough to support up to 750 horsepower on gasoline. This setup works well in high horsepower, high-rpm naturally aspirated engines and on power adder engines where a second pump is not needed.

450D - Features a pump module with a pair of Walbro F90000274 pumps that flow 450 LPH a piece and will support up to 1300 horsepower on gas. This dual pump setup is ideal for high horsepower turbocharged or nitrous setups on gasoline and can be staged to signal the second pump when additional fuel is needed under load or boost.
