Enderle Fuel Injection


INSTALLATION INSTRUCTIONS

  

TUNNEL RAM INJECTOR


PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING YOUR FUEL SYSTEM. If your injector was shipped directly from the factory, it should be set up for your application. A set of bypass jets is furnished which includes a jetting card showing the engine information and settings. The butterflies and metering valve are set before shipment. The metering valve is set using our leak tester. The leak percentage shown is specific to our leak tester only and will probably be different from other types of leak testers. 


GENERAL INSTALLATION

When installing the injector on the Manifold tighten the bolts evenly to prevent distortion. A gasket or silicone seal must be used on the bottom of the injector.


METERING VALVE

This metering system uses two return lines, each with a check valve. The check valve on the bottom of the metering valve is for the idle circuit and is set to open at 25 psi. The check valve in the tee fitting is the main jet return and opens at 1-2 psi. The main bypass jet is installed in the fitting under this check valve. A blank bypass jet is installed under the 9/16 hex plug on the metering valve and should not be removed.


MAIN BYPASS JET

Each fuel injector is furnished with a set of bypass pills. This bypass controls the fuel mixture at full throttle and has very little effect on the idle. Use a smaller bypass to richen the fuel mixture and larger bypass to lean it. When installing the bypass make sure it is seated at the bottom of the thread. Do not change the bypass jet to cure problems at idle. 


IDLE CONTROL

The idle mixture is controlled by the turnbuckle on the side of the injector. To richen the idle, rotate the turnbuckle towards the rear of the injector, (shortening the linkage leans the mixture, lengthening richens the mixture). This adjustment is for idle and throttle response only and has no effect on full throttle operation. The idle speed is controlled by the butterfly shaft stops on each end of the butterfly shaft.


MAINTENANCE

The fuel system should be drained between races. It is important to lubricate the fuel pump with LPS-3, WD-40, light oil or some other type of lubricant. Remove the inlet line from the metering valve and lubricate the metering piston to prevent stickiness and drying out.


GENERAL INFORMATION

A # 12 Inlet line should be used with a -1 size fuel pump. A # 10 inlet line can be used with a 0 or a ½ size pump, although a # 12 line will work with the smaller pumps also.

For best results the fuel pump should not be higher than the fuel level in the tank. Also, do not use a fuel tank mounted in the rear of the vehicle. The fuel tank must be in front of the engine.

Use a # 6 line form the pump to the metering valve and for the return lines. The return line must never discharge directly towards the tank outlet. The tank should have at least a 3 gallon capacity and should be vented with a 5/16” or larger hole.


TUNING TIPS

If the motor loads up at idle, the idle adjustment is too rich or the butterflies should be opened more.

If the response is hesitant, the idle is too lean. When running alcohol with an electronic ignition, the spark plug gap should be in the .020-.030 range.


WARNING

You must use a 3-way fuel shutoff with a return line to the fuel tank. A 2-way style shutoff will damage the fuel pump.

ENDERLE BLOWN  ALCOHOL INJECTOR


PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING YOUR FUEL SYSTEM. If your injector was shipped directly from the factory, it should be set up for your application. A set of bypass jets is furnished which includes a jetting card showing the engine information and settings. The butterflies and metering valve are set before shipment. The metering valve is set using our leak tester. The leak percentage shown is specific to our leak tester only and will probably be different from other types of leak testers. 


GENERAL INSTALLATION

When installing the injector on the blower, tighten the bolts evenly to prevent distortion. A gasket or silicone seal must be used between the injector and supercharger.


NITRO TYPE METERING VALVE

The idle check valve should be installed where the housing marked “RET”. The upper check valve is the high pressure pump relief and should also have a return line. The fuel line from the pump should be connected to the fitting marked “IN”. The line to the port nozzles should be connected to the fitting marked “PORT”.


METHANOL TYPE METERING VALVE

The idle check valve should be installed where the block is marked “OUT”. Connect the return line to this check valve. The fuel line from the pump should be connected to the fitting marked “IN”. The fitting in the rear corner of the metering valve should be connected to the top nozzle distribution block. Systems utilizing port nozzles will have an outlet fitting installed in the bottom of the metering valve.


IDLE CONTROL

The idle mixture is controlled by the turnbuckle on the side of the injector. To richen the idle, rotate the turnbuckle towards the rear of the injector, (shortening the linkage leans the mixture, lengthening richens the mixture). This adjustment is for idle and throttle response only and has no effect on full throttle. The idle speed is controlled by the butterfly shaft stops each end of the butterfly shaft.


MAIN BYPASS JET

Each fuel injector is furnished with a set of bypass pills. This bypass controls the fuel mixture at full throttle and has little or no effect on the idle. The bypass pill is located under 9/16 hex plug on the metering valve. Use a smaller bypass to richen the fuel mixture, and a larger bypass to lean it. When installing a bypass, make sure that it is seated at the bottom of the threads.


HIGH SPEED BYPASS SYSTEM

Certain applications require the use of a hi-speed leanout. This consists of a bypass jet controlled by a high pressure check valve which leans the fuel mixture at high rpm. The check valve pressure is adjusted with shims to tailor the fuel curve to the engines requirements. The check valve opens when the fuel pressure is able to overcome the spring tension. The bypass jet controls the volume of fuel returned. Adding shims will make the check valve open at higher rpm. Removing shims will cause the check valve to open at a lower rpm. The hi-speed should be though of as a fine tuning device. The main bypass jet is the primary control of the overall fuel mixture.


GENERAL INFORMATION

A # 12 inlet line should be used with a -1 size fuel pump. All 110 series pump require at least a #16 inlet line.

For best results the fuel pump should not be higher than the fuel level in the tank. Also, do not use a fuel tank mounted in the rear of the vehicle. The fuel tank must be in front of the engine.

Use a # 8 line from the pump to the metering valve. All return lines are #6. The fuel tank vent should be ½” or larger.


MAINTENANCE

The fuel system should be drained between races. It is important to lubricate the fuel pump with LPS-3, WD-40, light oil or some other type of lubricant. Remove the inlet line from the metering valve and lubricate the metering piston to prevent stickiness and drying out.


WARNING

You must use a 3-way fuel shutoff with a return to the fuel tank. A 2-way style shutoff will damage the fuel pump.

BLOWN GAS INJECTOR

The check valve in the tee fitting is the main jet return and opens at 1-2 psi. The main bypass jet is installed in the fitting under this check valve.

TUNING TIPS

Blown gas engines tend to be very sensitive to barrel valve and butterfly adjustments. Adjust the barrel valve only 1 or 2 flats of the hex bar at a time. If the idle is too lean, the throttle response will be hesitant and there may be a backfire through the butterflies. The exhaust may have some smoke at idle when the idle is set for good throttle response.


WARNING

You must use a 3-way fuel shutoff with a return line to the fuel tank. A 2-way style shutoff will damage the fuel pump.
