Fuel Intake

14.8.1 Pickup Body

Any impurities mixed with the fuel
are retained by the pickup body
(filter). The fine pores of the filter
eventually become clogged with
minute particles of dirt. This restricts
the passage of fuel and results in
fuel starvation.
In the event of problems with the
fuel supply system, always check
the fuel tank and the pickup body
first.
