Why Is Replacing Tomasetto LPG Filters Important?
Tomasetto LPG filters are designed to:
✔ Remove impurities from LPG fuel
✔ Protect LPG injectors
✔ Protect the pressure sensor
✔ Prevent deposits inside the reducer
✔ Ensure stable engine performance on gas
Failing to replace LPG filters on time may result in:
unstable operation on LPG
power loss
increased fuel consumption
injector malfunction
reducer damage
The cost of a Tomasetto LPG filter set is minimal compared to replacing injectors or a reducer.
What Does a Tomasetto LPG Filter Set Include?
A complete Tomasetto LPG filter set consists of:
1️⃣ Liquid phase filter (installed in the reducer)
2️⃣ Gas phase filter (installed on the hose after the reducer)
Gas phase filter materials may include:
Paper filter element
Polyester (higher filtration efficiency)
Foam (bulpren) – effective in retaining oil and paraffin residues
Polyester offers finer filtration, while foam is efficient at trapping oily residues commonly found in LPG fuel.
Recommended Replacement Interval
General recommendation:
✔ Every 10,000 – 15,000 km
✔ Or during each LPG service interval
Replacement intervals may vary depending on fuel quality.
Replacement Procedure
