only. Restrictors are precision-

 

 

 

 

 

 

 

 

 

 

machined parts and O-rings are rated for fuel contact.

 

 

 

 

Do not attempt to replicate or modify any parts. Refer to

 

 

 

 

Table 4.

 

 

 

 

 

 

The gun assembly is secured inside

 

 

 

 

 

 

 

 

 

 

 

 

the air tube by a spring-loaded

 

 

 

 

 

 

 

 

 

 

jacking screw. It is spring loaded in order to control the

 

 

 

 

force it can impose on the gun assembly. When installing

 

 

 

 

the jacking screw look inside the air tube to verify that

 

 

 

 

the pointed tip of the jacking screw pin is seated into the

 

 

 

 

small slot on the locating pad on top of the gun. There is

 

 

 

 

also an external verification of correct assembly: when

 

 

 

 

the screw is fully tightened, the e-clip on the top of the

 

 

 

 

center pin should come flush with the top of the screw.
