Abstract
A fuel pump apparatus for supplying fuel to an engine includes a lid member is formed divisionally from a first lid member having a fuel supply path, and a second lid member removably provided on the first lid member and having a fuel inflow path. A fuel filter is disposed between the first lid member and the second lid member. Since the fuel filter is built in the lid member, a protective case for protecting the fuel filter and a stay for attaching the fuel filter to a vehicle body are not required. The fuel pump apparatus so configured eliminates the requirement for a protective case for protecting a fuel filter and an attaching stay for attaching the fuel filter to a vehicle body and can achieve reduction of the cost.
Claims19
A fuel pump apparatus comprising:
- a pump,
- a tube member for accommodating said pump, and
- a lid member for closing up an upper opening of said tube member,
