[STL170]

I apologize for the long explanation, but here goes.

2006 170CC bought new in March 07

Including the test ride, my boat has died three out of four trips when idling for more than three or four minutes. The one time it did not die, I never let it idle more than 30 seconds and moved through the no wake zones at a minimum of 1200 rpm. The last time it died, we bypassed the filter with no luck. Finally put the hose from the primer bulb directly down the fill hole and it got us home with no problems including a 10 minute idle for my guest while I waited in line at the ramp.
My dealer is over 400 miles away and is also the closest to me. I called Triumph customer service for some assistance. I was asked to check the vent hose. I removed and inspected it and reattached the deck fitting end and blew and sucked through the hose to check the fitting. No problems. When I called back to report this to customer service, I was told that there had been a recall on the fuel pickup previously and he had parts ready to send to me. I received the parts which were the plastic pickup tube with screen, barbed fitting, aluminum elbow block and aluminum anti-siphon valve.
I removed the old anti-siphon valve to get room to spin the rest of the assembly. The aluminum threads galled inside the aluminum elbow on the way out. Unscrewed the elbow about ¾ of a turn and saw that the nut on the tank bulkhead fitting was starting to move. Put a wrench on the bulkhead and unscrewed the elbow another ½ turn before it locked up.
Triumph customer service says that all warranty work must go through the dealer. I had suggested using a portable tank until I visit my dealer while on vacation at the end of August. Customer service thought that was a good idea, but would not authorize any expense on my part. They would also not authorize any local service repair.
Any suggestions for service away from the dealer? I’m not comfortable running all summer with the bulb hose shoved down the fill neck.

Thanks
