Triumph TR7 Rover V8 Engine Conversion
|Step One: Replacing the fuel tank|
|RKC3523/E||fuel tank (two hole)||
When converting from a carburetted TR7 it will be necessary to replace the fuel tank with a two hole version if using a fuel injected Rover V8 engine.
Since genuine two hole tanks are now quite scarce, we supply a professionally modified single hole version. Your old tank is required in exchange and condition is generally not important since the firm that does this modification is also renowned for their fuel tank repair skills.
The tank is modified to accept a second TKC3408 sending unit in the right hand hole (as viewed above). The level sensor parts can be removed from the old sending unit and it is then used as a fuel return inlet. The fuel return line is installed using the clips in the existing holes in the handbrake support bracket at the top of the driveshaft tunnel.

|Step Two: Mounting the electric fuel pump|
The fuel pump arrangement is similar to the factory fuel injected TR7, TR8 models
It is mounted on the right rear bulkhead to the top right of the tranmission tunnel opening. The LH mounting bracket and pump/filter carrier brackets are not currently available, so it is necessary to fabricate something approximate as shown in the photos. The pump is a generic replacement by Airtex for multi point fuel injection systems and is widely available at local auto parts stores.
|Step Three: Modifying the Throttle Position Sensor (TPS)|
|ETC8495/K||throttle postion sensor kit||
The Range Rover TPS is not compatible with the GM TPI system.
Therefore, it is necessary to use a GM throttle position sensor (TPS). Since the Range Rover engine uses a shaft driven sensor, we decided to use the later rotary style GM TPS unlike the 'crank arm' style that the GM TPI cars used. This required an adapter plate and drive shaft as shown in the photos above.
|Step Four: Installing an air cleaner|
There is not much room left for an air cleaner, thus we decided to use a high flow aftermarket unit.
Starting at the plenum, the air hose is a stock Rover part. In place of a mass air flow sensor which would normally be between the hose and air cleaner, we placed an adaptor sleeve that houses the manifold air temperature sensor (MAT). The MAT sensor would normally be in the nine o'clock position - it is show at twelve in the photo for clarity. The MAT adaptor has two nuts welded to it to allow the assembly to be supported. We used steel tubes flattened at each end and bent to the appropriate angle, similar to the ones used to support the steering column.
