Oil & Fuel What is this on LS XR4140H fuel pump?

[neverfailyou]

Greasing and checking fluids on my 2017 XR4140H I have this port on the front of the fuel pump. What is it and is there any maintenance needed?

I checked the service manual and there is nothing in the fuel section or in the hydraulic section (that I could find). A phone call and text picture to my local LS dealer yielded no result?

Thanks in advance for any help.

Trying to add picture but seem to be technologically challenged!

Got the pic posted!

Isn't it the engine oil fill port missing the cap? Looks like a good spot for it and it's on the timing case.

Look like it to me as well.

Sure is. Straight from the owners manual:

Can you believe that the owners manual can actually answer some questions?

That’s it! I’m actually holding the cap as I take the picture.

How did I miss that? And I’m due to change oil in a couple hours of use…

Thanks for the quick response.

Ohhhh..... I thought this was going to be much worse! I was envisioning tons of dirt and grime filling the engine!
