Optimus Hiker + "greeny"

Here my new greeny Optimus Hiker +.

 

It appears that you have a pump type cap normally found on a smaller backpacking stove on the fuel tank. It will accept a mini or midi pump for improved performance. This cap is redundant in this case but would serve well on an Opti 8r or Svea 123.

 

I may be wrong, but is this not an SRV you're seeing there Harold?

Best regards,

Wim

 

can´t see any difference to this:

I am quite certain this is an SRV, designed to open at a certain pressure (when things get to hot).

Best regards,

Wim

 

The pump on this stove is the normal one.
There is certainly no need for a mini/midi pump.

 

Note however that Optimus had gone to a more standard hex rather than the pentagon hole for the cap SRV.
