GENERAL DESCRIPTION

When working on the fuel system, there are several
things to keep in mind:

•

Any time the fuel system is being worked on,
disconnect the negative battery cable except for
those tests where battery voltage is required.

•

Always keep a dry chemical (Class B) fire extin-
guisher near the work area.

•

Replace all pipes with the same pipe and fittings
that were removed.
Clean and inspect “O” rings.  Replace where
required.

•

Always relieve the line pressure before servicing
any fuel system components.

•

Do not attempt repairs on the fuel system until
you have read the instructions and checked the

pictures relating to that repair.

INJECTION PUMP

A Bosch Distributor Type Injection Pump is used.  A single reciprocating/revolving plunger delivers the fuel
uniformly to the injection nozzles, regardless of the number of cylinders.
The governor, the injection timer, and the feed pump are all contained in the injection pump housing.  The
injection pump is compact, light weight, and provides reliable high-speed operation.
An aneroid compensator is available as an option for vehicles to be operated at high altitudes.  It adjusts
the fuel and air mixing ratio.
A boost compensator is installed on turbocharger equipped vehicles.
