Ordered an o-ring kit from Partzilla. Bought an o-ring kit from Harbor Freight and tried that previously.

Bring it to hardware store ace or whatever you have near you they’ll usually have assorted o rings. Make sure it’s a tight fit or it’ll leak.

Fuel is 1.5mm x 8mm if memory serves, air is 2mm x 8mm. There are kits on eBay though with all the parts.
