Radium Multi Pump Fuel Surge Tank Dual Walbro F90000262 Gas Pumps Inc 20-0137-02 on 2040-parts.com

RADIUM DOES NOT OFFER A WARRANTY ON ANY FUEL PUMPS! FUEL PUMPS CAN BE RETURNED IN UNUSED CONDITION WITHIN 30 DAYS OF PURCHASE. 

A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. The FST fuel pump(s) feed the fuel rail(s). The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel. This volume is maintained by the main fuel tank's pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgrade any standard fuel system without opening the stock fuel tank. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.

The Multi-Pump Fuel Surge Tank Includes:

-Machined 6061 Aluminum Canister 
-Removeable O-Ring Sealed 6061 Aluminum Caps  
-Anodized and Laser Engraved  
-6AN O-ring Sealed Fittings 
-Calculated and Optimized Fuel Volume 
-Stainless Steel Hardware 
-Extra Machining for Weight Savings 
-Mounting Feet for Uneven Surface Installations 
-24" Flying Lead Color Coded Wiring Harness 
-Installation Instructions

The Radium Engineering Multi-Pump FST is constructed from 100% CNC machined 6061-T6 aluminum. It is anodized for long lasting protection from corrosive fuels such as ethanol.

The MPFST can be configured to use up to three fuel pumps. The Walbro F90000274 E85 pumps are shown above. The pumps are mounted using an anodized aluminum bracket. The fuel pump filter socks are retained. The FST incorporates a multi-pin high amperage sealed electrical bulkhead connector. All internal wires are gasoline, ethanol, and methanol compliant. The internal hoses are a special fluoroelastomer formulation that resists permeation internally and externally making it submersible in all types of fuel. 

Fittings
Green fittings signify the fuel pump outlets. These are bespoke adapters which are only available in -6AN male. The remaining black port fittings are used for fuel entering and exiting the tank. These are included in -6AN male as well. However, if -8AN and/or -10AN port fittings are required, they can be purchased separately. If only 2 pumps are used, a plug is included to cap the unused fuel pump outlet fitting. 

Selection:

The MPFST is available without pumps and prepped for the user to install their own pumps.

If pumps are needed, the surge tank will come pre-assembled with sock filters installed. Please select the preferred combination of pumps from the list. The MPFST is sold in 2 or 3 pumps configurations. If a single pump is required, please see our other FSTs available in the store.
