 INTAKE MANIFOLD AND EXHAUST MANIFOLD

 

The intake and exhaust manifolds are basically the
same as the once currently used.

EXHAUST PIPE

The exhaust pipe consists of three parts: a front
pipe, a center pipe, and a main muffler with muffler
cutter. It is mounted on the body via rubber hangers

Pre-muffler

to minimize vibration transmission from the exhaust
system to the body. A large main muffler, sub muffler
and pre-muffler reduce exhaust noise.

FUEL TANK

The fuel tank is the same as the one of the 420A
engine. (Refer to P. 1-12.)

The fuel tank is made from a high density polyethyl-
ene (HDPE) material and blow-formed into an inte-
gral tank.

The tank has an internally installed pump and gauge
assembly and pipe and gauge assembly. In addition,
a fuel cut-off valve assembly is provided to prevent
the leakage of the fuel that would occur when the
vehicle rolls over.
