Page 19 of 61 

For increased security, GPT offers a lockable enclosure to prevent tampering with the fuel filter 

housing. GPT part number 303657.

INSTALLING THE REGULATOR SUBASSEMBLY 

Apply thread sealant to the nipple threads as illustrated in Figure 10 to minimize fuel line 

contamination. Install the regulator subassembly to the safety shut-off valve through the opening on 

the floor of the instrumentation enclosure.

 

3.6

 

CONNECTING THE FUEL FILTER TO THE TEG 

Fuel to the Sentinel TEG is supplied through the fuel filter. Before connecting the fuel supply to the 

fuel filter, connect the fuel filter to the TEG as follows:

 

1.

 

Bend the straight section of the supplied 1/4” tubing to suit the distance and arrangement 

between the outlet of the fuel filter and the inlet to the ball valve on the TEG.  

2.

 

Connect and swage one end of the 1/4” tubing to the manual ball valve below the fuel regulator 

of the Sentinel TEG. 

3.

 

Connect and swage the other end of the 1/4” tubing to the Swagelok connector located above 

the flow arrow of the 

fuel 

filter.
