Capen) 3. 09:07 AM - Re: fuel valve (Brian Huffaker) ________________________________ Message 1 _____________________________________ Time: 08:48:58 AM PST US Subject: RV-List: fuel valve From: thomas sargent In doing my annual inspection, when I was running the engine to warm up the oil for an oil change, I tried to stop the engine by turning the fuel selector valve to OFF. It continued running without slowing down for what seemed like a long time (probably 1/2 to 1 minute) until I got tired of waiting and turned off the purge valve (AFP fuel injection) which stopped it immediately. The fuel flow gauge showed a steady 1.4 - 1.5 gph. Did I just not wait long enough or is the fuel valve worn out? It's the valve that Van supplied with the kit and otherwise shows no problems, doesn't feel worn, etc. -- Tom Sargent, RV-6A ________________________________ Message 2 _____________________________________ Time: 08:59:56 AM PST US From: "Ralph E. Capen" Subject: Re: RV-List: fuel valve I think you did not wait long enough....and the purge valve is right up there next to the injectors for an immediate cut-off. Residual fuel could still be pressurised by the mechanical pump and keep the engine running for a couple of minutes....mine ran for a while with the selector in the off position....while I was still creating my startup checklists... -----Original Message----- >From: thomas sargent >Sent: Jul 30, 2012 11:48 AM >To: rv-list >Subject: RV-List: fuel valve > >In doing my annual inspection, when I was running the engine to warm up the >oil for an oil change, I tried to stop the engine by turning the fuel >selector valve to OFF.

I once meant to switch tanks and switched the fuel off in flight, it took about 30 seconds before the engine stopped. Did start right back up again when I switched the fuel back on.
