The plug-in refuelers tend to continually give trouble.

The male end tends to get dirt on it and when inserted into the part on the plane, will make the internal plunger hang up and the engine will suck air.

The rubber O-rings supplied with the device do not hold up to glow fuel for extended periods of time.

The fuel dots method tends to be more trouble free.

Enjoy,

Jim, the rebuild kit comes with instructions. To get the old "O" rings out of the filler I used a "T" pin with a small hook bent on the end to hook the "O" rings and pull them out. Just don't scratch any of the metal surfaces. It really wasn't too complicated.

Here's the rebuild kit at Tower Hobbies.

I have several Du-Bro valves in service. They do not give me any trouble at all. If you are always sure to wipe the filler probe off before you stick it in, you wont scratch the o-rings with small bits of trash, the valves will not leak.

This is one reason why I only use fuel dots. They are leak proof and carefree.

I use YS engines like you (old 120 sf) in a Goldberg Extra 300 8.5 lbs and before a OS 120 four stroke

w OS 120 I turn 15X8 APC 8700 rpm 11.4 lb static thrust W 15 % power master
W YS 120 I turn 16X8 APC 9000 rpm 15.9 lb static thrust W 15% power master

can i see yours fuel dots ?

That is a strong YS 120. My Saito 150 can only get up to 8700 rpm turning a 16x8 with 15% power master.

Here are the fuel dots I'm using on my YS 63S:

The Saito 150 supose to be able to turn the prop a bit more then 120 ys aprox 9200 9300

I have had problems with the Dubro valve.I think the fuel dots are the way to go.

I have 3 valves and no leaks.

Sorry but I have to disagree with most here, refueling valves are a good option as they cut off fuel to the carb when refueling. It prevents flooding especially in inverted engines. Also, with refueling valves you can drain the tank properly. It does keep your car cleaner.

I do not use DuBro but rather some cheap Taiwanese one by Ming Yang I think. I have been using them for over 9 months and it does not leak at all. Only time it leaked was when I removed the probe too slow and the plunger did not come up properly. A normal tug will always ensure the plunger is sealed. I fly heck of a lot and never had any problems.

its great if you havent had problems with easy fuelers but once you do it sure makes the fuel dots look real good,especially if you run a cline regulator because it dont flood cause your cline shuts off your fuel to the carb.used both, love the dots!

I still use the Dubro fuel valve and I haven't had any problems with them leaking, the problem I have had is with them sucking air with the engine running and with the problems associated with this. To prevent this problem I do not run a fuel line to the engine from the fuel valve, I run only one line to the fuel tank and the line that goes to the engine I place a short piece of fuel line and plug it. I use 2 clunks in the tank with one to the fill valve and the other one to the engine supply, this also prevents air after refueling in the fuel line on my gas engines. I prefer this method over the fuel dots.

For those who might not already know, fuel dots are nothing more than end plugs for fuel lines.

Yes,I agree.I dont need at all those accessories unless for eastethic worries. U can use a suitable screw as a tap.But easy fueler is totally another thing.Great helper if functions properly.

By the way, prices on PSP site are for a pair of fuel dots and not just one.

I have been using the Kwik fill valves on my models for some time now without any problems, maybe I've just been lucky so far.

I use a two line system where one line is the vent, and the other goes from the clunk to the fill valve and then to the carb. Using fuel dots do seem to be a simple and trouble free arrangement, but how would they work in my two line system.

dubro quick fillers will all eventually leak. The Sullivan filler is bullet proof and will never leak: http://www2.towerhobbies.com/cgi-bin...?&I=LXFU75&P=0

Some buddys at the club have this dubro valves without issues with it, they put a bit of oil (after run or Klotz syntec)on the rubber rings and this way its easy to insert the nipple

I think: inserting the nipple in the dry rubber o ring is the way to start it leaking
