How to replace the injectors of a Landi Renzo LPG system

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

We can see in this video how to replace the LPG injectors of a Landi Renzo LPG system, installed as standard on a Fiat group vehicle. On this brand, Landi LPG systems are mounted exactly as we see in the video: on some models they are easily accessible as we see, while on others, even if the conformation is identical, they are mounted low so it is necessary to remove some components to access them.

The connectors are different depending on the EURO homologation of the vehicle, but in any case they are numbered to be reassembled in the correct sequence. This is very important, otherwise the vehicle will jerk and not run well.

Be careful when removing the plate, because the pistons still have pressure and can come out suddenly. Once removed, remember to grease the gasket well, so that it does not create friction with the seat.

Once the injectors are changed, we must also change the filter, both for the gas phase and the liquid phase. If it is an original system, no calibration will be necessary.
