RE: fuel filler
They will leak air...tomorrow or next year they will leak...besides you have to have that adapter that is pictured with it......A fuel dot and the 3 line system is almost fool proof......Good Luck

RE: fuel filler
Yes, i have had experience with one. I will never use one again. it is more toruble than it is worth. Mine leaked fuel and I've seem other people use them and eaither leak fuel or suck air into the system.
The valve is a neat idea but a regular old fuel dot is much simpler with far less chance of failure.

RE: fuel filler
I've got one on a plane for a year with lots of flights, no maintenance and zero problems (knock on wood). I also have a rebuild kit for when it eventually does get screwed up. In the end, like others said, a third line with a fuel dot is easier with little to no chance of going bad.

RE: fuel filler
Have used dozens of the DuBro brand ones, with few issues. Yes after several years they may need to be maintained with a new internal spring and o-ring. Very easy to do, have a friend who does it while still on the plane.

RE: fuel filler
the mentioned fuel filler is gonna leak, its not a question of if but of when.

RE: fuel filler
To each his own, I hate 3 line systems, unless you have a tank that allows for 2 clunk lines how do you empty the tank at the end of the day. I use only Hayes tanks and 2 lines systems with the DuBro fillers, as I said have had very few problems. If you like another set up so be it.

RE: fuel filler
I used to use those fillers on all my cowled planes years ago but over time they can and do leak or suck air, it happens most the time on planes that don't get used very often. The last one I had in a plane the little filler got stuck in the body of the unit and couldn't be removed. That was the day I went to the three line system.
If you don't mind seeing a small bit of fuel line on the outside of your plane then just use a two line with the carb line running on the outside of the fuse, cut it and use a piece of brass tub to attach the two halves together, shazam!! Your own custom filler, fool proof and free.
Fuel dots are just cleaner looking.

RE: fuel filler
Yup, I've had problems with them too.
The "O" ring is forced open whenever you insert the nozzle.
Sometimes it will crack causing a leak, or at worst particles to enter the fuel.
I've had both of these things happen.
IMHO this fueler is not worth the money.

RE: fuel filler
i use this setup and its fine but there is a tiny bit of fuel left sometimes depends on how much i'm willing to pump it out.
to drain the tank at the end of the day i lift the tail so the tank floor will be parallel.
on the tip of the vent and the fill line i put a small piece of fueling tube and cut two notches so it will keep a hole when its touching the top and bottom of the tank.
its not the perfect solution.

Also, you probably will not have to prime your engine as you will be force-feeding fuel right to the carb when fueling.

RE: fuel filler
Millertym,
I just setup a 2-line system with a T and fuel dot on my 50cc extra and it works fine,
you still have to prime the engine after fueling, atleast for the first start of the day.
Like ChuckW said it won't drip out the carb because of the pump on the Gas carbs.

RE: fuel filler
has it been 6 months allready, thats the time line for this topic to rear its ugly head again, well I have been diligently checking the fuel fillers notice(fillers) as in several there all working and not leaking so I guess I am the luckyest man in the world.
I would rather be, the most interesting man in the world, since he always seems to have the babes, but I will settle for lucky.
this seems to fall back on maintanence, if you let the fillers sit in fuel and gunk, for extended time, they gum up and the rubber O ring stops sealing properly, and seem suseptable to dammage resulting in the leaking of air and fuel, drain your tank and periodicly clean them and they work well for cowled planes where access to fuel lines are limited by space or the design of the engine compartment.
planes with fuelers I have airworthy.

RE: fuel filler
I have been using these fillers on petrol for a couple of months with no trouble. I only use mine as a filler with the brass pipe inside the fuel tank reaching to the bottom, so the filler can also be used to drain the fuel tank. Then I block off the filler's second nipple that would normally go to the carb with solder, as I prefer to feed the carb on a direct line from the fuel tank clunk to the carb, this way I need not worry about the filler failing, or pulling air into the carb. I then use a third line into the fuel tank with the brass tube inside directed to the top of the fuel tank which is then the 'full' over flow line and vent. So far this has worked well and keeps my fingers from getting covered in petrol.

If you do this, fuel will go to your carb as well as your tank. I had this setup, and found it best to hold my throttle-kill when turning off my plane, so that when I refilled or defueled the carb was closed and I was only pumping to the tank.
Also, you probably will not have to prime your engine as you will be force-feeding fuel right to the carb when fueling.

RE: fuel filler
Yes the conventional wisdom is that fuel fillers are really bad. I have had at least 2 dozen orver the last 20 years and may have had to "rebuild" 3 of them, a 5 minute job. Will add "fuel fillers bad" to my lsit of favorite RC myths, along with EZ keepers don't work and must only use fuel with castor oil. List is up to 11 now and just cracks me up how much bad info is passed along in this hobby based on these myths. I have 18 flyable gas and glow planes and 6 electric. In 20 years have owned about 60 planes, only crashed 2 beyond repair. I go to the field and my planes start and fly almost always, why, maitenance! Nothing will work well for long, especially aircraft, if not maintained. Drain the tanks, clean them up, check the bolts and horns etc., cycle the batteries, use your volt meter, iron out the wrinkles, patch the tears. The guys that come out and can't get an engine to run almost every time also are the guys who never fix anything! You are not lucky bigtim just paying attention.
