EFI Pump Module for Any Power Level

These days it’s easier than ever to build horsepower. Decades ago, a hot carbureted engine made 500 horsepower and was more than happy to be fed by the old-school electric fuel pump whirring away under the back bumper. But modern EFI engines can make that kind of power with little more than a cam swap, and they need that fuel delivered at more than 50psi. Bolt on a couple turbos or a supercharger and power levels can easily exceed 1,000 horsepower. A setup like this needs a serious fuel pump (or two). TwoLane™ EFI In-Tank Fuel Pump Retrofit Modules are designed to fuel modern EFI powerplants from mild to wild. 

Versatile Pumps and Versatile Packaging

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 car 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.

Some in-tank pump modules simply have holes for the plumbing that run straight into the top plate. These appear to be low profile until you start adding the fittings and adapters needed to connect the system and they can grow tall in a hurry. Not great for fitting under trunk and box floors. We’ve been bit by this in the past, so the billet lids on these TwoLane™ modules feature and AN-10 outlet fitting and AN-8 vent and return fittings that project from the billet housing parallel to the top of the tank, allowing for low profile routing of the plumbing that’s still sized big enough to handle just about any power level. 

Inside the tank, the adjustable bracket works on a wide variety of tanks, from 7-1/2” deep all the way up to 16". That means that these can be adapted into many stock-style EFI tanks as well as aftermarket tanks. 

Single 255 LPH Pump Delivers Reliable Performance

This in-tank EFI module uses the 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 cars with this pump feeding a variety of late model EFI V8 engines. In addition to the pump itself, this kit includes the billet 12-bolt top plate with fittings, 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 classic. 

Dual 255 LPH Pumps Support High Horsepower Engines

A single pump is great for stock and cam-swapped NA engines, but if you’ve added forced induction or nitrous, 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. This kit includes dual Walbro GSS340 255 LPH pumps, a billet 12-bolt top plate with fittings, dual submersible hose kits with clamps, dual fuel pump socks, dual wiring harness with relay-ready connectors, and all necessary mounting bracket and install hardware.
