NSS Lift Pump Spacer + Tuning Boost Pin + Dynamic Timing Advance Spacer Kit suitable for 200 and 300 Tdi engines

Boost Pin

Pin is made on CNC machines, accuracy of shape up to 0.01 mm. Material - Stainless Steel, hardened.

LDA - is a mechanism in the injection pump Tdi, which allows you to limit the amount of fuel at low revs, and the absence or low pressure boost. However, when the pressure rises to automatically give a higher dose of fuel. Eccentric pin which allows you to adjust engine settings.

Boost Plate

This spacer kit increases the range of the standard dynamic timing advance within the VE pump. The dynamic timing advance is a mechanism used to make the start of injection sooner as the RPM increases to give the Diesel time needed to properly combust.
The extra dynamic timing advance from this spacer kit will help to burn fuel cleanly at higher RPM while keeping your static timing to standard spec, maintaining low RPM performance.

Spacer is made on CNC machines, accuracy of shape up to 0.01 mm. Material: aluminium.

High quality Viton O-Ring, resistant to engine oils and high/low temperature.

The install of the spacer kit is straight forward just like the boost pin, but the acces is more difficult.

NSS Lift Pump Spacer

This spacer allows the lift pump to operate in the middle of its possible travel.

Using a spacer allows it to be fitted without interference with the high pressure diesel lines to the injectors. Precision laser cut from aluminium, with gaskets, bolts and washers.

Lots of people have asked what the benefits are to fittng a fuel spacer. The upshot is, adding a fuel spacer will elongate the life span of the pump.

Fuel pumps fitted to many diesel vehicles tend to snap their operating linkage, causing the vehicle to come to a stop.

Land Rover Tdi engines can still run (in the short term) with a broken pump but will experience symptoms of the vehicle being pretty poor starting from cold and you’ll probably get fuel starvation up hills.  The pump was originally designed to have a spacer but appears to have been left out due to a cost saving exercise.

Most people do not realise the pump is damaged until they attempt to change the fuel filter – You try to prime the fuel filter using the priming lever and nothing happens. This is because the pump is damaged. It has been operating right at the top end of its travel, causing strain. You then have to turn the engine by hand to find the one spot on the cam where the priming lever will operate.  By adding the fuel spacer, it allows the lift pump to operate in the middle of its possible travel, thus causing less strain. The priming lever should then operate regardless of the camshaft position.

Note: please note that we do not offer or imply any warranty with this, as it is a tuning part this is a tuning product will elevate the level of power in your engine. By running higher cylinder pressure will expose any engine weaknesses and they are sold on the basis that the purchaser fits entirely at their own risk.

We recommend fitting an exhaust gas temperature gauge so that you can monitor your engine exhaust temperature, tune and adjust accordingly.
