It's for an IO-320 with the Precision Airmotive fuel injection system. It's very simple - a lot more simplistic than I thought the whole system would be. I still haven't decided if I'm going with the Van's boost pump kit or the one from Andair yet. Any suggestions? :) Mike __________________________________________________________________ Looking for the perfect gift?

It is totally unnecessary and a real source of potential leaks. It cannot be the lowest point in the system, the lowest points are the tank drains, and the filter will take care of any debris. Personally, I would put the flow transducer inside the firewall down stream of the boost pump. This gives you a better chance to get a straight run up stream of it, helps to eliminate bubbles. This set-up has worked well for me through 4 RV's Bill On Sep 28, 2009, at 9:23 AM, Mike De Lange wrote: > Hi All, > > Here's a preliminary fuel system overview diagram for those who are > interested.

Bought an Auto racing pump, which in my opinion is as good as Van's. I picked up the check valve and the pressure valve at Sun N Fun a couple of years ago.I think the AN fittings ended up costing more that the rest of the components. However, After seeing Andair's pump, I going going with it and eliminating all those fittings and parts.

From: J Riffel Well, my canopy cracked - and I'm now replacing it. What have folks done with the bucktails inside the canopy frame? Each of the canopy frame sides, top and back pieces are closed so the bucktails fall inside when you drill off the canopy. I'm thinking of drilling another hole in each piece so I can get the bucktails out. Otherwise it'll sound like maracas with all the bucktails shaking around. Thoughts?

I know that the Andair pump is bound to be perfect (at around 600 American dollars), but the specs say 16gph @ 25psi. Any good running 180-200hp Lyc will flow more than that at sea level full power.....

Read my lips, "a gascolator doesn't have to be the lowest point in the system in order to do its job". Where did this crazy idea come from? Look at a gascolator closely and pretend you understand the physics of a heavier and more viscous fluid (water) settling out by gravity with the help of a screen tight enough to let the lighter less viscous fluid (fuel) preferentially float/flow thru. All a gascolator needs to work is to be installed correctly (with the bowl facing down and the curtis valve accesible for draining). You don't have to shake a rattle, do a chant or pray. It's science. -GV In a message dated 9/28/2009 10:12:53 A.M. Pacific Daylight Time, rvpilot@embarqmail.com writes: I suggest that you eliminate the gascolator.

When the first passenger flew, his jacket sleeve was being tugged at by the air leaking OUT at the upper rail where we had not sealed the slider canopy. What I'm saying is that the low pressure over the wing was pulling air out of the cabin from every available hole. When we sealed the canopy sides above the wing most of the other areas were much more managable. We used some "V" seal with the opening blocking the direction of flow which is Out above the wing and IN along the rear skirt. Some other type seals also work, like "P" seals where the "bulb" is flexable enough move in the direction of air flow and get pushed against skirt or skin. I hope this helps; many builders have never dealt with this area first. Best wishes, Stan VanGrunsven RV-6A April 1998 ----- Original Message ----- From: Ian To: rv-list@matronics.com Sent: Thursday, September 24, 2009 10:37 AM Subject: RV-List: Leaky air inlets on RV-9A My RV-9A is starting to chill my wife! As the weather gets cooler we've noticed significant amounts of air coming in through the control stick holes and also out of the edges of the mounting of the eyeball vents. The Van's drawing calls for the removal of the fourth hole on the mounting (the one you would catch your leg on) and this seems to result in a slightly open joint, especially under air pressure. What have others done about both problems. I realize putting a boot over the stick will help that area, but unfortunately I just bought nice looking automotive gear shift boots that have lots of fancy little holes in them! Any ideas for what material would be light, flexible and draughtproof?? Beautiful flying day!
