LPG Gas Filter Kit Prins VSI 2x Outlet 16x11x11mm for Prins VSI-3 with eVP Type 1 Reducer

Replace the gas filter in time and regularly!

The filter lasts a maximum of 20,000 km. Preferably replace the filter earlier.
This replacement period applies with an average engine capacity of approximately 1.8L. Larger engines use more gas, which means the gas filter needs to be replaced sooner.
It is also possible that the LPG contains a lot of contamination (with oil and fats) at some refueling, which means that it is necessary to replace the filter earlier. Take this into account.
The timely replacement of the gas filter is necessary to prevent contamination of the gas system and gas injectors.

TIP!

Use 2 filters one after the other (in series) instead of just 1 filter. This allows you to prevent the contamination of the injectors even more when driving on a polluted LPG quality, for example. In this way there is a second filter that can still catch the excess paraffin.

In most cases the problem is caused by the fact that the injectors are contaminated with paraffin (oils and greases from the LPG). The filter in front of the injectors must ensure that the injectors do not contaminate quickly. This filter will eventually become saturated and must be replaced every 20,000 km. If the filter is not replaced, the paraffin will no longer be trapped and end up in the injectors. It is not the case that the injectors leak or do not open anymore. But the opening and closing time are no longer correct. The injectors remain open longer than they should (with dynamic behavior), which means that too much fuel is being dosed. (too rich mixture) The injectors will then deviate, especially with short injection times (low engine load). The engine is going to run messy and there are too large differences between the injectors. Cleaning the injectors often makes no sense, because there is often too much wear in the injector occurred, as a result of which the guide of the plunger (sealing disk) no longer has the right fit. The plunger does not go smoothly and lord, but goes up and down stumbling and wobbling. If the injectors are replaced without replacing the filter, the new injectors will soon become dirty again.
