Late model EFI engine swaps and aftermarket EFI systems are hot right now—and it’s no secret why. With the ample supply of parts and kits from the aftermarket, you can make ridiculous power and do it more affordably than ever with these conversions.
Until now, though, the fuel system has been a costly and time-consuming upgrade for these swaps. Block mount pumps aren’t an option on today’s engines, carbureted fuel pumps are not going to work with EFI, and the tanks in these cars are not designed for EFI pumps. The most realistic options have included installing a fuel cell, welding in a big sump on your tank, or fabricating a custom fuel tank. While all of these options will work, they can be very expensive, require a lot of work, and may just not be what you want.
We first showed you this system back in November at the SEMA Show. It’s a complete kit that gives you everything you need to install a fuel pump and baffle/basket into almost any fuel tank. The system is built around Aeromotive’s in-tank 340 Stealth Fuel Pump, which is capable of handling serious power even at EFI pressures. You also get a black anodized hanger assembly and an internal baffle to control fuel slosh and keep the fuel pump submerged. The best part, this entire system is modular and can be cut to height to fit almost any tank, including your stock tank.
Why In-Tank Is Better
By using an in-tank fuel pump, you virtually eliminate hot fuel handling issues like cavitation and vapor lock because the pump is constantly submerged, taking advantage of a column height of fuel on the inlet of the pump. And, because of the innovative baffle or basket, you can control fuel slosh and keep fuel at the pickup point (the pump) at all times—even with low fuel levels and in extreme driving conditions!
Aeromotive‘s Stealth Fuel Pump is capable of handling up to 700 horsepower from supercharged EFI applications or 1,000 horsepower from carbureted supercharged engines. You can switch between carbureted and EFI with nothing more than a regulator swap. You can also use your factory tank or a reproduction to maintain that stock look while enjoying the performance you demand.
