the pressure is maintained. It is apparent that this control band is acceptable, however it could be improved.
When replacing internal fuel hoses, make sure you select a hose that is suitable for immersion in petrol, most fuel hoses are not.
When replacing a pump or filter care should be taken to keep the connecting hoses clean. If you have to remove the tank, cap or cover the ends of the hoses immediately after disconnecting them.
The 4mm grub screws that secure the base ring to the tank, are prone to corrosion and can prove difficult to remove, a little anti seize grease should be applied to the screw. It is not necessary to completely remove the screws when removing the base ring from the tank, but they have to be withdrawn clear of the locating groove in the tank.
The filler cap is not sealed from the base ring, water from washing or rain is free to enter the base ring cavity from where it drains. The drain pipe can block, when this happens the cavity fills up and a surprising amount of water will enter the tank next time the cap is opened. If you notice that fluid not draining, clean out the tube.
Another cause of failure to drain is a kink in the hose between the base ring and the steel tube that runs through the tank. This hose and the vent hose can be readily observed through the tank fill aperture
Some models came fitted with quick dry break connectors on the fuel hoses, these make tank removal much easier. Models that are not equipped can be retrofitted. The couplings are manufactured by
Colder Products .
When fitting, consider reversing the orientation of one connector, this will make it impossible to incorrectly connect the fuel lines.
Throttle Position Sensor calibration is essential as the ECU uses the feedback to determine mass flow.
When modifying the intake or exhaust systems, it is unlikely that the ECU map would be suitable. As this can not be adjusted, it requires that means of adjustment has to be provided. Several devices exist that fitted into the control circuit can modify the pulse width according to its own inbuilt (and adjustable) map
Replacement ECU’s are also available that give complete and finer control over all parameters.
