Thumbnail Filmstrip of Surge Tank Mount Underhood Mechanical Fuel Inj MECHANICAL PUMP W REAR TANK Images
Surge tank for Mechanical or EFI systems when main tank is in the rear. ALTERNATIVE TO OUR WATERMAN CABLE DRIVE
*************** ONLY 8" Wide x 5" Wide x 13" tall ***********
FOR EFI SYSTEMS ORDER IT WITHOUT THE FLOAT AND YOU CAN LET IT OVERFLOW BACK TO THE MAIN TANK
TOP MOUNTED FLOAT NEW DESIGN
Mechanical Injection on the Street or Race when using a Rear Mounted Tank -
For rear tank vehicles, and Road Race cars. Use your Electric pump to fill up the surge tank,
then the injection pump draws it's fuel from the surge tank.
Works with EFI systems using mechanical pump to prevent having to use a cable drive rear mounted pump. Don't need the float when using it for EFI
Can use Gasoline- E-85-E-98- Methanol *
Should drain the methanol out after each use *
Has 2 -12AN Female holes in bottom - you fill it from the bottom and feed the pump from the bottom
we can put a -10 -12 -16 -20 in the bottom
Billet Construction -100% Welded
Comes with 12 Volt Relay for wiring up the float to the fuel pump -
Can be filled from the top or bottom
Internal Stainless float will turn electric pump on and off as it fills
Allows you to use an rear electric pump to move fuel to the front so that a mechanical injection system pump can be used without starving for fuel. *
Hooking it up without a relay WILL destroy the float- no guarantee for floats that are shorted out- we test each one when installing it .
Has two (2) built in return ports for your by pass valves to return the fuel to.
Has a large breather vent port on top.
Float is easily removed to service, clean, or replace if needed.
Is constantly being filled from your electric pump, as well as your returned fuel.
Has optional billet mounts that are able to be moved for convenient mounting.
Recommend a large electric fuel pump for filling - Holley Black or Larger

Highly recommend venting this tank back to the main tank in the event of an overflow it will then overflow back to the rear tank- you can install our rollover vent in the tank, but could suffer fuel overspill if the float ever sticks.
The Tank specs below :
Holds approximately 2.20 gallons.
5" Wide x 8" Wide x 13" Tall Rectangular
Wiring Instructions for Surge Tank Float
Surge Tank Wiring Diagram MUST USE RELAY FLOAT WILL BURN UP OTHERWISE
12 volt positive from key or fuel pump on/off switch will land on terminal 86
12 volt positive with large enough wire to support fuel pump needs will land on 30.
87a will run to 12 volt positive on fuel pump itself. Ground of fuel pump can be run to battery or chassis if chassis is grounded.
Ground will need to be supplied from battery or chassis to level switch in tank. Other lead of level switch will land on terminal 85.
In many cases you have to connect 30 and 86 together to complete the wiring.
