However the left one doesn't work at all because the metal muffler bracing either is not wide enough when bent to achieve the necessary height to keep the exhaust pipe up. Or it interferes with the heating duct. Not sure if I am the only one with this issue and what is wrong. Any ideas anyone.

We fill up after every flight but we leave each tank down by 2 gallons. We do this so it doesn't vent out the normal vents onto the floor. There isn't much expansion room in these tanks. I've heard of fuel coming out the key hole but if it happens to us it's very rare. I very much doubt you would loose a meaningful amount of fuel. I've never seen any water get in. --Dave Saylor 1015 hrs On Apr 7, 2012, at 23:44, "dmaib@me.com" wrote: > > > Bob Turner wrote: >> I don't have these caps but it sounds to me as if there is a design defect, or perhaps an O ring that needs replacing. >> >> Since the fuel caps are on the top of the wing, a low pressure area, they will siphon fuel out if they leak at all. This will also make the fuel pump work harder, especially if the normal vent can't keep up with the pressure loss out the top. And if gas can get out, then rain can get in. >> >> Fuel caps shouldn't leak. > > > I certainly agree that caps should not leak. But, all of these caps installed on RV-10's seem to do this. I can't imagine it is an o ring problem when this seems to be a fleet problem limited to RV-10's. So, I would lean towards the design defect, except that it does not seem to be a problem on other types of aircraft.

I ended up cutting the lower hanger bolt (the one on the end of the cable) and snugging up the brackets such that I had the shortest overall length between the bent hanger and the exhaust attach point. Cutting the lower bolt is needed as the end hits the exhaust attach point long before you run out of threads. I also mounted the bent hanger as high as possible. Combined these solved the problem.

I agree that the amount of fuel vented is not significant, but it makes a mess on the wing with the blue dye. Full tanks will definitely lose fuel through the vent tubes as fuel expands with rising temperatures. I've seen that happen on many different airplanes. I may try modifying my vent tubes with a couple of coils, like my tip tank vent tubes. I can't see why that should make a difference, but I guess it is worth a try. -------- David Maib RV-10 #40559 Transition Trainer Read this topic online here: http://forums.matronics.com/viewtopic.php?p=370287#370287 ________________________________ Message 6 _____________________________________ Time: 09:01:56 PM PST US Subject: RV10-List: Turboprop RV10 From: "woxofswa" http://www.avweb.com/avwebflash/exclusivevids/ExclusiveVideo_SunNFun2012_DiemechDieselEngine_206389-1.html -------- Myron Nelson Mesa, AZ Emp completed, QB wings completed, legacy build fuse in mostly done, finishing kit in progress.

Of course W&B and fuel capacity will need some minor adjustments.

Just thought it was interesting. The 210k cost difference, fuel burn difference, insurance difference, etc, just doesn't add up to me. Not that anything in aviation makes sense, but if gotta have a turbine, you can buy an MU-2 for the cost of that motor. -------- Myron Nelson Mesa, AZ Emp completed, QB wings completed, legacy build fuse in mostly done, finishing kit in progress.
