Fuel intake

14.8.1 Pick-up body

Any impurities mixed with the fuel
are retained by the pick-up 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 trouble in the fuel
system, always check the fuel tank
and pick-up body first.
– Troubleshooting, b 4.6 or
b 4.7.
