RE: Wren 54 SS problem
I sent my Wren SS into Ron for service late July ......I dumb thumbed while starting, tipping my propane can and dumping in liquid propane. Cooked the front bearing before I figured out what was going on. His service was excellent. Great communication from the first call until he sent it back repaired. Turnaround was 7 working days, door to door.
Sure sounds like you are having a fuel pump issue with yours. No doubt Ron will fix you up in short order.
