Fuel Tank Inlet Filter

I would like to find a fuel filter that works at the fuel tank inlet catching dirt etc. before it gets in the tank. I of course have the little tiny screens at the petcock inlet and the screen at the 2011 carb inlet. I have seen Guglatech filler cap filters advertised for other bikes, but none for KLRs.

Due to the locking bar of the KLR fuel cap you probably won't find an in-tank filler neck filter bag to Install & Forget! May have to remove it after each fill-up.

But I also know that you are a 'pretty crafty' old fart!

I just stuck a caliper into the neck of a Gen 1 and measured 1 & 11/16". Next I have a Twin-Air 160610 filler neck filter sock to fit KX250 - 450 F models.
The OD of the sock attachment black plastic measures 1 & 3/4". If the upper flange was segmented and the sock attachment was mostly 'slit' it might pass thru the upper neck and engage the lower neck.

This Fuel filter sock had a retail price of $34.95 when I ordered it, sometime back.

A quick measurement on mine showed 1.63". Close to the 1 & 11/16" you measured. I am thinking I will not find a perfect fit, but the Twin-Air 160610 would drop in well enough to filter from a nozzle or a funnel. I could then drop the the filter into a mesh sack tied to the back of my tail box.

The cheesecloth idea really speaks to the MacGyver in me.

Plus, it's inexpensive and you could easily replace it periodically. However, I'm not familiar with the cheesecloth mesh size, but, hopefully, it's a decent size for filtering fuel.
