Follow the schematic carefully; read all the small notes. It would be a good idea to install a 15-PSI gauge to monitor the VST pressure. Install it between the VST and the Back Pressure valve. The pressure at an idle should be 3-4 PSI. This pressure should not drop below 1-PSI at maximum RPM wide open throttle operation. COMPONENTS : ADVANTAGES OF THE VST SYSTEM NO squirt bottle, NO open fuel containers, one person operation, easy to install Automatic priming of the fuel injection system from the drivers seat. The pressure in the Vapor Separator Tank purges out all the vapor. This pushes the fuel through the mechanical injection pump. When the main fuel shut- off is opened, the fuel flows directly into the engine. When the engine starts it will stay running because all the fuel system hoses are purged out. Gone are the problems of having to try and start the engine three or four times, this is hard on the starter, battery, and some- times a persons ego (nothing hardly worse then being at a race or show and having the engine start, pop, bang, and die several times). The VST system is less expensive than other “fixes” on the market. It takes up less room, and is not affected by G-forces. Each valve is stamped on the end to identify it as seen on this Back Pressure Valve... stamped “BP” Electric fuel pump wiring: wire the electric fuel pump into the ignition switch, so that the pump cannot run when the ignition is shut “off”. PLUS install a separate pump switch in the circuit so even when the ignition is “on”, the pump can be shut off. It is important NOT to run the pump when the engine is shut “off”, fuel could drip from the nozzles and eventually flood the engine. APPLICATIONS The VST system is often used on road race cars, marine applications, off-road cars and trucks, street cars, and sometimes on drag cars with rear mounted fuel tank, both for constant flow and EFI systems. Used by top race teams all over the world including Daytona, Sebring, and LeMans. It is usually used with gasoline, however it can be used with alky, which requires special maintenance and/or hardware. Call a Kinsler technician for details. © 2017 Economizer Valve has a small metering orifice drilled in the center of the poppet make certain is stays clean NOTE : Specify 8 AN, 10 AN, or 12 AN outlet to mechanical injection pump when ordering. Tanks are available with 8 AN or 10 AN male flare inlet (supply from electric pump) and 6 AN or 8 AN male flare for return to Back Pressure valve - other sizes can be special ordered.
