M151A2 Emission Tank Fuel Valve Covers Wanted

[m75]

I was wondering why the A2 emissions fuel tank -34P only lists one valve guard (2910-01-138-0916, 11613719) required, when there are three similar hard line inlets for the tank? Same bolt pattern and size. Since the driver's seat is right above these connections, wouldn't it make sense for all three to have this vent guard?

I'm looking to acquire two of these items.

Figure 29, item #9 in the -34P.

The reason is probably because it is under the lowest part of the seat at the rear. The front of the seat has plenty of clearance. And anything sliding forward from the rear would contact there first if it got past the seat frame.
