Fuel Filter: See Figure 6-28. The fuel filter removes
rust and scale and other solid particles from the
LPG liquid to keep them from embedding in the
valve seats of the shutoff valve and pressure regu-
lator and causing them to leak. A magnet traps iron
and rust particles and a filter element traps non-
magnetic particles.
Disassembling
and
Cleaning the Fuel Filter:
1.
Purge the LPG system as instructed in Section
5.
Preparing to Service.
2.
Remove the four capscrews and lock washers
that hold the filter bowl to the filter body.
3.
Separate the filter bowl from the filter body and
discard the
0-ring
seal.
4.
Remove the nut and washer from the center
stud and pull out the filter element.
5.
Wash the filter element
in
solvent to remove the
particles it has collected. Blow it dry with low
pressure (30 psi
I 207 kPa) compressed air.
Replace the filter element if damaged.
