Sorry flatbeddennis that it took so long to respond to your question, but yes I have two planes with the fueling valves and I just plug in and fuel and nothing goes to the carb.

Are you telling me that you just plug in the nipples and fuel up and no fuel at all goes to the carb. I got 2 in a row that flood my carb 99% of the time.
Dennis

Fossil,
Hobby services sent me 2 replacements and today the first one leaked fuel to the carb 3 out of 5 fuel ups. I give up.........
Dennis (red bluff)

I have two working as well. One is on a Saito 80 and the other is on a 46fx. The one on the 46fx is 4 years old and sat for 3 of those years after a year of use, still works perfectly. I can see the fuel lines and not one drop ever enters the line going to the carb.

I love 'em!

Man thats bad both of mine are 2 years old and work great.

Model Airplane News-Jan 2002 has a very good solution to the fueling problem on page 16, the "Tips &Tricks"section. Inexpensive too! Sporty

Fossil, Do you use an electric pump ? Im beginning to wonder if my Hobbico pump is too much for the fueler. Maybe I can put a voltage dropping resistor in line to slow it down for a test. I will play with that therory and post the results.
Dennis
Real planes have two wings and radial engines...........

Dennis, you could be on to something there. I am using a 12 year old electric pump. I am sure this thing is not working like it used to, it could be the reason why both of my easy fuelers work. Lets see what fossil says.

I do have to admit, I have a Yuasa battery for a Kawasaki 900 in my flight box and my Hobbico pump really cranks. The extra current sure starts the Saito 72 nicely but might be too much for the pump/fueler situation.
Dennis
Real planes have two wings and round motors.........

I don't think its the electric pump, mine leaked even after I removed the nipple from the valve. The 6 shooter I am using does not produce the same volume as the hobbico related ones do.

I *had* one of these on my ME-109 It lived for about a year, and dies two weekends ago after I swapped out the old engine (OS .52) for a new engine (YS .53). It worked for about 30 seconds, then blew up. (one of the fuel nipples detached)

Fuel everywhere!

I replaced the old valve with a new one and tried again. This one fell apart while fueling up!

Pulled the fueler out, ashcanned it.

I now have a set of fuel dots installed. I have a 'T' in the carb line for fueling, one line for return pressure and a third which I uncap as a vent. Works great.

Well, I flew this am for a while, managed to get the fueler to work 3 out of 5 fuelings. Slowing the pump with a resistor had no effect. I wish I knew exactly whats in there so I could diagnose the symptoms. I just dug one out of the trash, going to cut it open with the dremel. Will post results.
Dennis

Here it is....Not much. 2 "o" rings (1 small,1 large), a cone shaped piston and a spring. With a small pin bent on the end, pull out the first "o" ring, with small hemostats extract the piston and spring and then the smaller "o" ring. I also found what appears to be a curved 1/2" long piece of hair. How bout that......I wonder whats in the one thats on my plane now. Guess I will do a little excavation and see what treasure I can find. (Upon closer inspection, the hair like strand might be plastic or nylon).
Dennis (Red Bluff, Ca)

I use an electric pump, but I may have made a mistake. After closer look my fuelers they are DuBro not GP. I thought they were GP but I saw an add for the GP valve and realized mine are a little different.
fossil

OK, I dissassembled the one thats in my plane and hosed it out with my fuel/pump and it worked fine all nite. I fueled up 5 times tonite after the cleaning with no problem. I'll be darn..........
Dennis (Red Bluff)

Hi d4, are you using the ones from gp or dubro ? Thx.........

I've been informed that Dubro makes the Great Planes Easy Fueler, but who knows. Also, it seems that everyone having good luck with them also says that they have had them for years. The Great Planes units im having trouble with are brand new...
Dennis (Red Bluff)

Let me get this straight, if I decided not to use a filler valve but instead a T with a fuel dot then making sure the carb is fully closed I will have no worry of flooding? This this apply to all engines?

Randy

yeah I was wondering about THIS.

Zigi

I've had about five or seven fuelers over the years, a mixture of Dubro and GP. Never had a problem.

Hi rcflier, did you have to service them at all, i.e. open them up to replace the o-rings and spring ? .............

Tonite was the last draw. I can't remember ever having this much trouble with anything. I put in the last replacement fueler, it worked 1 time correctly and leaked to the carb on the 2nd fueling. I disconnected the lines and ran them outside the cowling and coupled them together with a short piece of brass tube. Problem solved !!!!! I flew and fueled at least 5 or 6 times and that disconnected fueler didn't leak a drop. I think that made a total of 4 GREAT PLANES EASY FUELERS in a row that leaked to the carb of my new SAITO 72. Oh well.....
Dennis (Red Bluff)

The probability of getting 4 bad ones in a row is kinda slim. I suspect that you have your connections to the 2 nipples reversed. This will mean that your fuel will be pumped to the carb instead of the tank. Another possibility is your pump pressure is too high. Just my 2cents.......

I tried everything, and they were all hooked up right. I even slowed the pump down with a voltage dropping resistor. I know alot of people who have these fuelers and they work great for them, so, Im going to just accept the fact that my Super (picky) Stearman / Saito 72 does not like them. Maybe more releif in the vent line might of helped, but I didn't think of that at the time. I have a simple coupler in the line now and it works fine. Perhaps I will play with it again at a later date, but for now, Im running out of hair to pull out and just want to fly. I left the fueler in the cowl just in case I get bored and need something to stimulate my brain. Dennis (Red Bluff)

I never serviced any of them. But I tend to keep a plane for one season and then sell it and if it is equipped with a fueler it gets sold with it.

BTW: The Robart super fueler is a nice unit. Not sure if they make them anymore.

Folks, here's an x-ray pic of the gp fueler which I took few months back out of curiosity. No I didn't pay for it. It was taken in my lab. Go figure how it works and why it doesn't in your case. BTW there are two o-rings if you can see them.............
