The invention concerns a fuel system (1) for supplying pressurised fuel, in particular dimethyl ether (DME) or a blend thereof, to an internal combustion engine, said fuel system (1) comprising a fuel pump (4), which has a pumping mechanism (10, 11) arranged partly in a housing (16) containing lube oil, a drain line (24) connected to said housing (16) and suitable for draining at least fuel vapour from an interior of said housing (16), a lube oil supply line (22) connected to said housing (16), a lube oil supply valve (31 ) installed in said lube oil supply line (22), a seal (21) installed between said pumping mechanism (10, 11) and said housing (16) for preventing at least lube oil leakage to the outside of said housing (16), and a drain valve (30) installed in said drain line (24), wherein both said drain valve (30) and lube oil supply valve (31); are controlled to be closed during an engine non-running state for preventing fuel vapour leakage from said housing (16).
