While often not practical to be viewed while driving, the indicator can be used for diagnosing a potential fueling issue.Ģ0-0519 includes all of the items shown in the following picture. When the fuel level switch is triggered, the signal is sent directly to the LED.

If the 20-0519 Fuel Level Switch Plus Diagnostic Indicator can be used as a visual reference for fuel level. Apply PTFE thread sealant to the tapered 1/8' NPT threads when installing.Ģ0-0519 Fuel Level Switch Plus Diagnostic Indicator Polarity can easily be reversed by removing the E-clip and flipping the float. It includes 24' long, 20AWG flying leads. The level switch is constructed of corrosion resistant stainless steel compatible with all fuel types. When fuel level in the MPFST drops by 20% or more, a switched signal can be sent to a unit such as a dashboard mounted indicator or programmable ECU input for safety purposes. When the plug is unscrewed, this 1/8' NPT fuel level switch can be installed from underneath, as shown below. The Multi-Pump Fuel Surge Tank comes standard with a 2AN ORB plug in the 'level switch' port, as shown below. Information is provided HERE on fuel pumps offered by Radium Engineering. The brushless Ti Automotive E5LM MPFST is designed for 1 or 2 pumps (shown below).

The MPFST comes ready for the end user to install 1, 2, or 3 pumps. Stainless steel M6x1.0mm socket head bolts are included for custom mounting. Necessary ring terminals and hardware are included with every surge tank.Īs shown, the underside of the MPFST is suitable for uneven surfaces commonly found in the trunk of a vehicle.

The pump power connections are handled with specially designed high-current electrical studs. The brushless Ti Automotive E5LM MPFST (shown above) utilizes a standard press-in filter sock included commonly with the pump (or HERE).Īll other (brushed pumps) pumps use the provided stainless steel mesh inlet screen for pre pump filtration shown above.

All internal wires are gasoline, ethanol, and methanol compliant. The pumps are mounted using an anodized aluminum bracket. When fuel enters the MPFST through the 'SUPPLY' and 'RETURN' ports, it gets redirected and runs tangential through the canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance. The brushless Ti Automotive E5LM MPFST pump outlet merge collector shown below. All of these fittings can be swapped out with different sizes (sold separately). This 'PUMP OUT' port is 10AN ORB threaded but comes preinstalled with a -8AN male adapter fitting. The 'OVERFLOW', 'SUPPLY', and 'RETURN' ports are all 8AN ORB threaded but come preinstalled with -6AN male adapter fittings. NOTE: The brushless Ti Automotive E5LM MPFST includes check valves (shown below in green). Multiple high flowing fuel pumps can be used in the surge tank.īecause the compatible pumps utilize a check valve, the MPFST merges all pumps into a single outlet simplifying external plumbing. Recently redesigned for 2019, the Radium Engineering MPFST is the perfect solution for high power vehicles experiencing fuel starvation during aggressive driving.

The surge tank also provides a quick and easy way to upgade any standard fuel system without opening the stock fuel tank. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. This volume is maintained by the lift pump as well as the fuel returning from the fuel pressure regulator. The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel, even if the lift pump starves momentarily. Fuel is supplied to the surge tank by a lift pump, which in most cases is the OEM in-tank fuel pump. **Need help selecting which fuel pump configuration?
