But the upgraded ones have doublers. Just have to find out if they started like the 1100lb CH or the 960lb CH. What is a 3X gun?

Just disconnect the lines to the wings at that point. Having said this I need to add that I have never disconnected them and would not recommend this if you plan to remove the wings a lot unless you put some type of quick disconnect as opposed to just pushing the lines onto a nipple. It would be difficult sending pics of my installation. I ran the lines inside the cockpit from the two selectors down along the steel cage on either side of the windshield, through the firewall and to a single gascolator at the lowest point on the firewall. This is the lowest point in the fuel system and the lines run downhill from the tanks so that water could not collect anywhere else than the gascolator. From there I ran the fuel lines up through a fuel flow meter and an aux electric pump (which I have never had to use) to the engine. I was concerned that putting the gascolator forward of the firewall could lead to vapor locks.. Not so; I have 250 flight hours, some of it in 105+ air temps without any problems.

Simple and safe. Les Les I am installing Aux. tanks also and that is my idea also "selectors at wing root Main/Aux/off" then to the normal gascolator and to a firewall shutoff. My question for you is what selectors did u use and can u share pics of your instlation? Also is there any problem with the selectors at the wing root and removing the wing?

I recognize that there are less expensive alternatives but the traffic information the 330 provides to the GRT Sport EFIS seems a wise choice given the difficulty in seeing a polished aircraft.

That eliminates the only problem I have found with this cable setup, other than the springs and maybe I will learn to live with that. Initially, it was easy to pull the throttle beyond the intended idle with just the stops at the carbs. There hasn't been any sync creep with this setup so far, it's still nice and smooth. Time will tell if it is the ultimate solution, so far it looks promising...

The fuel flow sensor added about $100 to the cost of my Dynon engine monitoring. When I fill up now I rarely have to add over a quarter-gallon more or less than the Dynon tells me that I have used. Also, we have discussed the uneven draw from the tanks in earlier threads. I always fly with both inner tanks or both outer tanks open so that I can=92t forget to switch tanks. My tanks may drain unevenly because my autopilot uses the ailerons to steer the plane, which means the wings are not always level. Frankly I won=92t worry about this unless I=92m low on fuel because if one tank empties the plane should just draw from the other one. However, I have never been really low on fuel and the tanks have never had more than a 4-gallon difference to see what would happen.

My 701 with only the main valve (floor valve), will always use first the gasoline from the right wing. No problem in short flights (less than an hour), when the plane is parked both tanks will even in a few minutes. In long XCountry flights (more than 2.5 hrs a leg) this has worked for me: Take off with both side valves open, for security, at cruise altitude I close the right tank for one hour (in use the left tank), at one hour, I open the right valve (keep both valves opened for the rest of the flight) and when landing I always land with both tanks (almost) even. For "Simplicity and lightness" I should only add the right wing valve, left one never closed for balance fuel. I always plan my flights for less than 3 hrs a leg... I get a little nervous when the "trusty" electric needles get close to 1/4... :-) :-) Here there are only a few landing strips, less with gasoline available.

I can easily reach each valve and use it to balance fuel use between tanks. I added a note in my preflight checklist to make sure all fuel valves are on for takeoff. Dan Wilde > > Too true Curt but that is the only way to control your fuel and proper fuel managment is part of flying. General aviation is full of fuel related incidents as well as commerical aviation. I'm trying to reduce other fuel related problems excessive fuel imbalance can be just as dangerious as fuel starvation. My thinking on the two fuel selectors at the wing roots is it's very visable (I.E.unlike John Denver's) and easy to get at. > > Reguards.
