I ordered a set of OEM o-rings for the fuel T, which are damn near impossible to find. Which seems to be the case for a lot of the first gen parts. For example, the o-ring for the water pump is rarer than bigfoot. Some guys on a Hurricane page gave me a link for an o-ring supplier who carried an OEM spec ring for the fuel T. I paid about $20 with shipping for a set of 2 OEM, and about $12 for a pack of 50 for the aftermarket OEM spec.
**UPDATE** OringsAndMore just got back to me and have a suitable item for the water pump. I ordered a few so I'll have spares. ****
I have a few other parts that will be printed, handguards, head light ears, switch mounts, and maybe a new gauge cluster with a sun shield. The material is PETG, which is like ABS but without the nasty VOCs and sensitivity to drafts. I found a cool tool box but with how long it will take to print, I may just buy a tool tube.
