Default Andair Boost Pump Leak

I've been chasing an issue where air was getting into my fuel line causing cold start issues where a cylinder will drop off due to getting a slug of air. Weeks of changing lines etc and I finally decided to cap the Andair tank selector lines and pressurize the airframe side from the firewall with 10psi. Squirted some soapy water and found this:







Has anyone else had one of these pumps leak? It is leaking from a joint on the body where the bubbles can be seen. Been in service 7 months.

Spoke to Andair on the phone this morning. Owen said there is an o-ring in there but they will need it back to fix it. Will fedex it out this morning. None of these in stock anywhere in the states. I certainly did not desire to build a single point of failure into my plane with replacement parts half a world away. When I bought this pump Spruce stocked them. Backordered at present though. Something to consider if you're building.
