Dual EFI Pump Under-Car Surge Tank
Polished Finish, Use With AF49-1014 Pumps

These Aeroflow Performance Under-Car Surge Tanks are designed to prevent starving the fuel pump by increasing the fuelling capability of the fuel system. It is usually installed in vehicles that potentially can experience fuel starvation due to fuel sloshing around in an inadequately baffled fuel tank/cell. While this can occur in any vehicle when the tank is not fully filled, it is more frequent in vehicles subject to violent changes in directions such as autocross, off-road, drag racing and other types of racing that involve high g-force. The primary fuel pump in the vehicle's main fuel tank will no longer directly feed the engine. Instead, the internal fuel pump will now be used to fill and maintain the level of fuel in the surge tank itself. Using a surge tank will now require new external fuel pump/s to be installed after the tank to supply fuel to the engine.

These compact EFI surge tanks are designed to work with our AF49-1014 fuel pumps, which have a 60mm body and are similar to the popular Bosch Motorsport 044/200 (Sold Separately). These smart little tanks are designed to have fuel pumps submerged in fuel for a quieter operation and longer life of the fuel pump.

This surge tank is specifically designed to be mounted under the vehicle in a horizontal position. It should not be installed inside the vehicle or in a vertical position.

The tank itself is robotically TIG welded with 2.5mm thick aluminium, featuring three female -8 O-ring ports. When both fuel pumps are installed, you can fit a AF939-08-10 billet Y-piece to merge both fuel pumps to a single female -10 ORB port.

The tank is available in either Polished or Black anodised finishes. Black anodised is recommended for Ethanol or Methanol fuel systems. A block off plate is also included so you can run a single pump rather than the dual setup.

Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself. The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that. The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
