A fuel surge tank (FST) is designed to prevent starvation to the engine on vehicles with inadequate fuel tank baffling. The surge tank also provides a quick and easy way to upgade any standard fuel system without the need to modify the stock fuel tank or pump. It is also an excellent fueling solution for vehicles installing large fuel demand power upgrades such as forced induction.
PLUMBING
All adapter fittings on top of the FST are 6AN (9/16"-18) male.
1. The internal FST pump directly feeds the fuel rail(s), through the green 6AN bulkhead fitting. The pump outlet fitting is available in -6AN male size only.
2. The 3 black (interchangeable) 6AN ORB fittings are used for the following.
a. Fuel entering the FST (from the lift pump)
b. Fuel overflowing and leaving the FST (to main tank)
c. Fuel returning from the fuel pressure regulator
NOTES:
1. An internal flow deflector prevents fuel foam and aeration on all 3 ports.
2. The pumps mount internally using tubing that is gasoline, ethanol, and methanol resistant.
3. The overflow to the main tank is a requirement on all installations. Tanks without return ports will need customization of the hanger top or filler neck to create a port for the overflow.
